KVM: PPC: Book3s: Remove real mode interrupt controller hcalls handlers
Currently we have 2 sets of interrupt controller hypercalls handlers
for real and virtual modes, this is from POWER8 times when switching
MMU on was considered an expensive operation.
POWER9 however does not have dependent threads and MMU is enabled for
handling hcalls so the XIVE native or XICS-on-XIVE real mode handlers
never execute on real P9 and later CPUs.
This untemplate the handlers and only keeps the real mode handlers for
XICS native (up to POWER8) and remove the rest of dead code. Changes
in functions are mechanical except few missing empty lines to make
checkpatch.pl happy.
The default implemented hcalls list already contains XICS hcalls so
no change there.
This should not cause any behavioral change.
