libpayload/arm64: Support FEAT_CCIDX
ARM SoC supports FEAT_CCIDX after ARMv8.3. The register field
description of CCSIDR_EL1 is different when FEAT_CCIDX is implemented.
If numsets and associativity from CCSIDR_EL1 are not correct, the system
would hang during mmu_disable().
Rather than assuming that FEAT_CCIDX is not implemented, this patch
adds a check to dcache_apply_all to use the right register format.

BUG=b:317015456
TEST=mmu_disable works on the FEAT_CCIDX supported SoC.
