[PATCH v5 04/17] xen: Relocate mem_event_op domctl and access_op memop into common.

[Tamas K Lengyel <tklengyel@sec.in.tum.de>]

Signed-off-by: Tamas K Lengyel <tklengyel@sec.in.tum.de>
---
v5: Move memop compat into common as well.
    Position domctl in switch relative to the domctl #.
v4: Don't remove memop handling from x86_64/compat and style fixes.
