This patch fixes a bug which was introduced in commit
3065513 related to improper saving of EL1 context in the
context management library code when using 128-bit
system registers.
Bug explanation:
The function el1_sysregs_context_save still used the normal
macros that read all the system registers related to the EL1
context, which then involved casting them to uint64_t and
eventually writing them to a memory structure. This means that
the context management library was saving EL1-related SYSREG128
registers with the upper 64 bits zeroed out.
Alternative macros had previously been introduced for the EL2
context in the aforementioned commit, but not for EL1.
Some refactoring has also been done as part of this patch:
- Re-added "common" back to write_el2_ctx_common_sysreg128
- Added dummy SYSREG128 macros for cases when some features
are disabled
- Removed some newlines

The rse_platform_api.h file includes certain MbedTLS headers,
introducing an unnecessary dependency when building the TC
platform with RSE support unconditionally.
However, these headers are not required, as the BL31
implementation only initializes RSE communication,
which does not rely on MbedTLS.

Other component such as OP-TEE may have the responsibility for
STGEN configuration but updating Arm CNTFRQ can only be done from
EL3. Therefore, implement a SiP SMC handler for this purpose and
a runtime service to catch SIP SMCs.
