refactor(cm): couple el2 registers with dependent feature flags

Currently the EL2 part of the context structure (el2_sysregs_t), is
mostly feature dependent.

For instance, CTX_HCRX_EL2 is only needed when FEAT_HCX
(ENABLE_FEAT_HCX=1) is set, but the entry is unconditionally added
in the EL2 context structure and thereby consuming memory even in
build configurations where FEAT_HCX is disabled.

Henceforth, all such context entries should be coupled/tied with
their respective feature enables and be optimized away when unused.
This would reduce the context memory allocation for platforms, that
dont enable/support all the architectural features at once.

Further, converting the assembly context-offset entries into
a c structure relies on garbage collection of the linker
removing unreferenced structures from memory, as well as aiding
in readability and future maintenance.

fix(cpus): workaround for Cortex-X4 erratum 2701112

Cortex-X4 erratum 2701112 is cat B erratum that applies to
revision r0p0 and is fixed in r0p1. This erratum affects
system configurations that do not use an Arm interconnect IP.

The workaround for this erratum is not implemented in EL3.
The erratum can be enabled/disabled on a platform level.
The flag is used when the errata ABI feature is enabled and can
assist the Kernel in the process of mitigation of the erratum.

feat(tc): get the parent component provided DPE context_handle

Each client who wants to communicate with the DPE service
must own a valid context handle issued by the DPE service.
A context handle can be used for a single time then it will
be invalidated by the DPE service. In case of calls from
the same component, the next valid context handle is
returned in the response to a DPE command. When a component
finishes their job then the next component in the boot flow
inherits its first context handle from its parent.
How the inheritance is done can be client or
platform-dependent. It can be shared through shared
memory or be part of a DTB object passed to the next
bootloader stage.

refactor(arm): console runtime switch on bl31 exit

Any BL31 setup and Runtime initialization within BL31 is still part of
the BOOT process. As such, the console flush and switch must be the
last calls before BL31 exit. Flush the console print buffer before
switching to runtime. This is so that there is no lingering chars in
the print buffer when we move to the runtime console.

This patch adds console flush before switching to runtime in
bl31_plat_runtime_setup() function (before BL31 exits). The plan is to
move flush and switch calls to bl31_main before BL31 exits, until then
console_flush() in bl31_main.c has been left as is.

This patch affects the Arm platform only.
