From: Simone Ballarin <simone.ballarin@xxxxxxxxxxx>

to prevent the contents of a header file being included more than
once").

Changes in v4:
- Drop ARCH_ string from the guard, according to the feedback received
Changes in v3:
- remove trailing underscores
- change inclusion guard name to adhere to the new standard
Changes in v2:
- drop changes in xen/arch/arm/include/asm/hypercall.h
- drop changes in xen/arch/arm/include/asm/iocap.h since they are
  not related with the directive
