KVM: x86: Move PIT ioctl helpers to i8254.c

Browse source

Move the PIT ioctl helpers to i8254.c, i.e. to the file that implements
PIT emulation.  Eliminating PIT code in x86.c will allow adding a Kconfig
to control support for in-kernel I/O APIC, PIC, and PIT emulation with
minimal #ifdefs.

Opportunistically make kvm_pit_set_reinject() and kvm_pit_load_count()
local to i8254.c as they were only publicly visible to make them available
to the ioctl helpers.

No functional change intended.
