In mt8186 suspend/resume flow, ATF has to communicate with a subsys by
read/write the subsys registers. However, the register region of subsys
doesn't include in the MMU mapping region. It triggers MMU faults.
This patch extends the MMU region 0 size to cover all mt8186 HW modules.
This patch also remove MMU region 1 because region 0 covers region 1.

Cortex X2 erratum 2058056 is a Cat B erratum present in the X2 core.
It applies to revisions r0p0, r1p0, and r2p0 and is still open.
There are 2 ways this workaround can be accomplished, the first of
which involves executing a few additional instructions around MSR
writes to CPUECTLR when disabling the prefetcher. (see SDEN for
details)
However, this patch implements the 2nd possible workaround which sets
the prefetcher into its most conservative mode, since this workaround
is generic.

Add 'firmware' node in morello-soc.dts to expose SCMI
support to the kernel. The SCMI protocols supported at
the moment are SCMI Base, Clock and Perf (DVFS).
The current mailbox memory region in MHU SRAM has an issue
with any access not aligned to a 4-byte boundary. So, the SCMI
mailbox memory region has been relocated to AP non-trusted
RAM to get around the problem.

ENABLE_FEAT_FGT and ENABLE_FEAT_ECV macros are used to access
HDFGRTR_EL2 and CNTPOFF_EL2 registers respectively. These flags are set
to true for v8.6 and upwards and are not handled explicitly for lower
architecture versions.
This patch adds definitive default value to these build macros, so that
for v8.5 and below, they are not overridden and set to true by the gcc.
