The xen sources contain violations of MISRA C:2012 Rule 14.4 whose
headline states:
"The controlling expression of an if statement and the controlling
expression of an iteration-statement shall have essentially Boolean type".

Add comparisons to avoid using enum constants as controlling expressions
to comply with Rule 14.4.

Changes in v2:
- rename patch prefix from AMD/IOMMU to x86/IOMMU;
- move changes on hpet.c and msi.c from xen/x86 to x86/IOMMU patch;
- rename patch prefix from xen/x86 to xen/x86_emulate.

Maria Celeste Cesario (2):
  x86/IOMMU: address violations of MISRA C:2012 Rule 14.4
  xen/x86_emulate: address violations of MISRA C:2012 Rule 14.4
