arm: Check FEAT_CCIDX when parsing ccsidr_el1 register
Current Cache Size ID Register (ccsidr_el1) has two "flavors"
depending on whether FEAT_CCIDX is implemented or not.
When FEAT_CCIDX is implemented Associativity parameter
is coded on bits [23:3] and NumSets parameter on bits [55:32].
When FEAT_CCIDX is not implemented then Associativity parameter
is coded on bits [12:3] and NumSets parameter on bits [27:13].
Current U-Boot code does not check whether FEAT_CCIDX is implemented
and always parses ccsidr_el1 as if FEAT_CCIDX was not implemented.
This is of course wrong on systems where FEAT_CCIDX is implemented.
This patch fixes that problems and tests whether FEAT_CCIDX
is implemented or not and accordingly parses the ccsidr_el1 register.
