Philippe Mathieu-Daudé 62271205bc hw/isa/piix4: Migrate Reset Control Register
When adding the Reset register in commit 5790b757cf we
forgot to migrate it.

While it is possible a VM using the PIIX4 is migrated just
after requesting a system shutdown, it is very unlikely.
However when restoring a migrated VM, we might have the
RCR bit #4 set on the stack and when the VM resume it
directly shutdowns.

Add a post_load() migration handler and set the default
RCR value to 0 for earlier versions, assuming the VM was
not going to shutdown before migration.

Fixes: 5790b757cf ("piix4: Add the Reset Control Register")
