On Hikey960 if outputs GPIO176 low level, it can tell PMIC to power off
the whole board. To avoid resetting the board and stay off, it also
requires the SW2201's three switches 1/2/3 need to be all set to 0.
Since current code doesn't contain complete GPIO modules and misses to
support GPIO176. This patch adds all known GPIO modules and initialize
GPIO in BL31, and adds system power off callback to use GPIO176 for PMIC
power off operation.

Since now the generic console_t structure holds the UART base address as
well, let's use that generic location and drop the UART driver specific
data structure at all.

There exists a third DMA controller on the hi3660
SoC called the IOMCU DMAC. This controller is used by
peripherals like SPI2 and UART3. Initialize channels 4-7
as non-secure, while 0-3 remain reserved and secure.

Many parts of the code were duplicating symbols that are defined in
include/common/bl_common.h. It is better to only use the definitions in
this header.
As all the symbols refer to virtual addresses, they have to be
uintptr_t, not unsigned long. This has also been fixed in bl_common.h.

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

LOAD_IMAGE v1 to simplify code.

When some interrupts are configured as group 0 in GICv2, these
interrupts trigger FIQ signal; this results in the Linux kernel panic
by reporting log: "Bad mode in FIQ handler detected on CPU0, code
0x00000000 -- Unknown/Uncategorized". Unfortunately from kernel side it
has no permission to read the GIC register for group 0 interrupts so we
have no chance to get to know which interrupt is configured as secure
interrupt and cause the kernel panic.
For upper reason, this commit enables FIQ exception handling for
SPD_none case. If the system has not enabled SPD the FIQ interrupt is
trapped into EL3 and the FIQ handler can report the interrupt number so
we can easily narrow down which FIQ introduce unexpected interrupt.
After enable SPD we can rely on SPD interrupt route model to handle FIQ.
