target/arm: convert isar regs to array

Browse Source

The isar in ARMCPU is a struct, each field of which represents an ID
register.  It's not convenient for us to support CPU feature in AArch64.
So let's change it to an array first and add an enum as the index of the
array for convenience.  Since we will never access high 32-bits of ID
registers in AArch32, it's harmless to change the ID registers in
AArch32 to 64-bits.
