target/arm: Store TCR_EL* registers as uint64_t

Browse source 
Change the representation of the TCR_EL* registers in the CPU state
struct from struct TCR to uint64_t.  This allows us to drop the
custom vmsa_ttbcr_raw_write() function, moving the "enforce RES0"
checks to their more usual location in the writefn
vmsa_ttbcr_write().  We also don't need the resetfn any more.
