Compiling with -Wimplicit-fallthrough=3 (enabled by -Wextra) produces
many warnings about fallthrough comments either missing or being wrong.
Unify the comments so we comply with -Wextra.
Note that Coverity recommends against using the __attribute__ directive.
Also, zlib does not build with a higher value of -Wimplicit-fallthrough.
Finally, compilers strip comments before expanding macros. As such,
checkpatch's fallthrough annotation (or higher levels of the flag) isn't
really possible.

This patch discards all the used entropy bits from the global memory
pool after being delivered to the requester (lower exception levels) by
overwriting them with zeroes.
It effectively implements the requirement, as part of TRNG FW interface
listed at DEN0098 (section 1.2).

This patch adds X2-X6 and 'smc_ret' parameters to trp_rmi_handler().
The last 'smc_ret' parameter passed in X7 contains address of
'trp_smc_result' structure on stack to return result of RMI SMC call.
This allows to preserve X4 if not used as a return argument as per
SMCCCv1.2. The patch also removes use of trp_args_t in RMI handling.

This patch fixes an issue in spmc_ffa_fill_desc.
In order to compute the spmc_shm_get_v1_1_descriptor_size,
fragment_length which is a fraction of the descriptor size is used as
desc_size parameter. It has to be replaced with the
full V1.0 descriptor size(obj->desc_filled).
Ran a subset of our tests and they are passing.

The current implementation expects that the endpoint IDs of all
participants of a memory transaction to be listed in the relinquish
descriptor. As per the FF-A spec, aside from the current partition
ID, only the IDs of stream endpoints whose behalf it is relinquishing
the memory region must be specified.
The current implementation does not currently support proxy endpoints
therefore ensure that the endpoint count is always equal to 1 and
no stream endpoint IDs are specified and instead just verify the
caller is a valid participant in the memory transaction.
Additionally reuse the updated check in the retrieve request flow
for additional verification.
