Since we only support 64-bit hosts, there's no real need
to parameterize TCG_TARGET_REG_BITS. It seems worth holding
on to the identifier though, for documentation purposes.
Move one tcg/*/tcg-target-reg-bits.h to tcg/target-reg-bits.h
and remove the others.

Drop a block containing sanity check and fprintf error message for

Setting ARMCPU::gt_cntfrq_hz in hvf_arch_init_vcpu() is
not correct because the timers have already be initialized
with the default frequency.
Set it earlier in the AccelOpsClass::cpu_target_realize()
handler instead, and assert the value is correct when
reaching hvf_arch_init_vcpu().
