This patch adds an argument to bl1_plat_post/pre_image_load() APIs
to make it more future proof. The default implementation of
these are moved to `plat_bl1_common.c` file.
These APIs are now invoked appropriately in the FWU code path prior
to or post image loading by BL1 and are not restricted
to LOAD_IMAGE_V2.
The patch also reorganizes some common platform files. The previous
`plat_bl2_el3_common.c` and `platform_helpers_default.c` files are
merged into a new `plat_bl_common.c` file.
NOTE: The addition of an argument to the above mentioned platform APIs
is not expected to have a great impact because these APIs were only
recently added and are unlikely to be used.

Hynix ufs has deviations on hi36xx platform which will result
in ufs bursts transfer failures at a very low probability.
To fix the problem, the Hynix device must set the register
VS_DebugSaveConfigTime to 0x10, which will set time reference
for SaveConfigTime is 250 ns. The time reference for SaveConfigTime
is 40 ns by default.

The Arm Trusted Firmware is built by default for ARMv8-A version 8.0.
However, the Foundation FVP runs by default in the highest version of
the architecture it supports. This causes problems when trying to run
the Arm Trusted Firmware on it.
This patch adds a note to the User Guide about this problem.

Previously the definition of `_tzc_read_peripheral_id()` was wrapped
in ENABLE_ASSERTIONS build flag. This causes build issue for TZC400 driver
when DEBUG=1 and ENABLE_ASSERTIONS=0. This patch fixes the same by
moving the definitions outside the ENABLE_ASSERTIONS build flag.

After executing a TLBI a DSB is needed to ensure completion of the
TLBI.
rk3328: The MMU is allowed to load TLB entries for as long as it is
enabled. Because of this, the correct place to execute a TLBI is right
after disabling the MMU.

Commit fdb1964c34 ("xlat: Introduce
MAP_REGION2() macro") added a granularity field to mmap_region_t.
Tegra platforms were using the v2 xlat_tables implementation in
common/tegra_common.mk, but v1 xlat_tables.h headers in soc/*/plat_setup.c
where arrays are being defined. This caused the next physical address to
be read as granularity, causing EINVAL error and triggering an assert.
Consistently use xlat_tables_v2.h header to avoid this.

According to the SMC Calling Convention (ARM DEN0028B):
The Unknown SMC Function Identifier is a sign-extended value of
(-1) that is returned in R0, W0 or X0 register.
The value wasn't sign-extended because it was defined as a 32-bit
unsigned value (0xFFFFFFFF).
SMC_PREEMPT has been redefined as -2 for the same reason.
NOTE: This might be a compatibility break for some AArch64 platforms
that don't follow the previous version of the SMCCC (ARM DEN0028A)
correctly. That document specifies that only the bottom 32 bits of the
returned value must be checked. If a platform relies on the top 32 bits
of the result being 0 (so that SMC_UNK is 0x00000000FFFFFFFF), it will
have to fix its code to comply with the SMCCC.

This fixes all defects according to MISRA Rule 3.1: "The character
sequences /* and // shall not be used within a comment". This affects
all URLs in comments, so they have been removed:
- The link in `sdei_state.c` can also be found in the documentation file
`docs/sdei.rst`.
- The bug that the file `io_fip.c` talks about doesn't affect the
currently supported version of GCC, so it doesn't make sense to keep
the comment. Note that the version of GCC officially supported is the
one that comes with Linaro Release 17.10, which is GCC 6.2.
- The link in `tzc400.c` was broken, and it didn't correctly direct to
the Technical Reference Manual it should. The link has been replaced
by the title of the document, which is more convenient when looking
for the document.

Function plat_ic_get_pending_interrupt_type() should return interrupt
type, not id. The function is used in aarch64 exception handling and
currently the irq/fiq forwarding fails if a secure interrupt happens while
running normal world.
The qemu-specific gic file does not contain any extra functionality so it
can be removed and common file can be used instead.

At present, the build option TSP_NS_INTR_ASYNC_PREEMPT controls how
Non-secure interrupt affects TSPs execution. When TSP is executing:
1. When TSP_NS_INTR_ASYNC_PREEMPT=0, Non-secure interrupts are received
at the TSP's exception vector, and TSP voluntarily preempts itself.
2. When TSP_NS_INTR_ASYNC_PREEMPT=1, Non-secure interrupts causes a
trap to EL3, which preempts TSP execution.
When EL3 exception handling is in place (i.e.,
EL3_EXCEPTION_HANDLING=1), FIQs are always trapped to EL3. On a system
with GICv3, pending NS interrupts while TSP is executing will be
signalled as FIQ (which traps to EL3). This situation necessitates the
same treatment applied to case (2) above.
Therefore, when EL3 exception handling is in place, additionally
require that TSP_NS_INTR_ASYNC_PREEMPT is set to one 1.
Strictly speaking, this is not required on a system with GICv2, but the
same model is uniformly followed regardless, for simplicity.
Relevant documentation updated.
