My previous patch set for replacing feature bits with id registers
failed to consider that these id registers are beginning to control
migration, and thus we must fill them in for KVM as well.

Thus, we want to initialize these values within CPU from the host.


Changes, v3->v4:
  * Drop THUMB2EE patch; will revisit next development cycle.
  * Fix aa32 id_isar6 read on old kernels (pmm).

Changes, v2->v3:
  * Work around sysreg read failures from old host kernels.

Changes, v1->v2:
  * Remove assert that AArch32 sysreg <= UINT32_MAX.
  * Remove unused local variable.
  * Add commentary for AArch32 sysregs vs missing AArch32 support.
