* changes:
fix(plat/marvell/a3720/uart): do external reset during initialization
feat(plat/marvell/a3k): add north and south bridge reset registers
fix(plat/marvell/a3720/uart): configure UART after TX FIFO reset
feat(plat/marvell/a3720/uart): preserve x1/x2 regs in console_a3700_core_init()
Sometimes when changing UART clock from TBG to XTAL, UART HW enters into
some broken state. It does not transit characters from TX FIFO anymore
and TX FIFO stays always empty. TX FIFO reset does not recover UART HW
from this broken state.
Experiments show that external reset can fix UART HW from this broken
state.
TF-A fatal error handler calls console_a3700_core_init() function to
initialize UART HW. This handler may be called anytime during CPU
runtime, also when kernel is running.
U-Boot or Linux kernel may change UART clock to TBG to achieve higher
baudrates. During initialization, console_a3700_core_init() resets UART
configuration to default settings, which means that it also changes
UART clock from TBG to XTAL.
Do an external reset of UART via North Bridge Peripheral reset register
to prevent this UART hangup.

These registers make it is possible to do external resets of A3700
peripherals. Most peripherals are reset by clearing a particular bit,
but some need setting the bit. Reflect this via "_N" suffix in macro
names.

If TX FIFO is not empty, do not touch UART settings and let UART HW
transmit remaining bytes from TX FIFO. New UART settings are then set
only after TX FIFO is reset.

Followup changes will need function arguments in registers x0, x1 and
x2. Do not modify x1 and x2 registers and instead use scratch x3 and x4
registers for storing local variables.

Commit 4333f95 ("fix(spm_mm): do not compile if SVE/SME is enabled")
introduced a comiple time check to verify if ENABLE_SVE_FOR_NS is set to
0 when SPM_MM build is enabled. To support SPM_MM builds on SGI/RD
platforms set ENABLE_SVE_FOR_NS to 0.

In fixup_gdt_reloc(), do not skip the last address (__RW_END__) for
dynamic relocations.
Else, the invalidation of the data done under _init_c_runtime in
el3_entrypoint_common macro will not be correct.

Adds support for SPMD with SPMC at S-EL1. A new config option SPMC_OPTEE
is added to support loading the special OP-TEE images when configured
with SPD=spmd. With or without SPMC_OPTEE. It should still be possible
to load another BL32 payload implementing a SPMC, provided that entry
point is the same as load address, that is, BL32_BASE.

The RMI command handling in RMMD did not preserve x4 to x7 when
returning to NS caller. Although this is allowed for SMCCCv1.0, this is
not correct as per v1.1. This fixes the same by differentiating the
onward and backward path during SMC handling.
This patch also fixes an issue with the backward path wherein the first
argument was being truncated to 32 bits.

The previous codes were using the cntpct_el0 to check the time
elapsed. But this physical timer does not seem to count for
the expected time resulting in gic fmu communication failures
on Tegra platforms.
This patch uses the delay_timer instead to use a platform
defined timer for calculating timeouts.
