Vikram Mulukutla 404b5a97f5 ARM: qcom: scm: Flush the command buffer only instead of the entire cache ...

scm_call flushes the entire cache before calling into the secure world.
This is both a performance penalty as well as insufficient on SMP systems
where the CPUs possess a write-back L1 cache. Flush only the command and
response buffers instead, moving the responsibility of flushing any other
cached buffer (being passed to the secure world) to callers.
