fix(bl1): invalidate SP in data cache during secure SMC
Invalidate the SP holding `smc_ctx_t` prior to enabling the data cache
when handling SMCs from the secure world. Enabling the data cache
without doing so results in dirty data either being evicted into main
memory, or being used directly from bl1. This corrupted data causes
system failure as the SMC handler attempts to use it.
