[XEN PATCH v2 1/3] xen/arch/arm: fix violations of MISRA C:2012 Rule 3.1

[Nicola Vetrini <nicola.vetrini@xxxxxxxxxxx>]

In the files `xen/arch/arm/include/asm/arm(32|64)/flushtlb.h' there are a
few occurrences of nested '//' character sequences inside C-style comment
blocks, which violate Rule 3.1. The patch aims to resolve those by removing
the nested comments.

Changes:
- Resending the patch with the right maintainers in CC.
Changes in V2:
- Split the patch into a series and reworked the fix.
- Apply the fix to the arm32 `flushtlb.h' file, for consistency
