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. Reference: - https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/12770 BUG=b:317015456 TEST=mmu_disable works on the FEAT_CCIDX supported SoC.
