[PATCH] misra: add deviations of MISRA C Rule 5.5

[Dmytro Prokopchuk1 <dmytro_prokopchuk1@xxxxxxxx>]

MISRA C Rule 5.5 states that: "Identifiers shall
be distinct from macro names".

Update ECLAIR configuration to deviate:
- clashes in 'xen/include/xen/bitops.h';
- clashes in 'xen/include/xen/irq.h';
- clashes in 'xen/common/grant_table.c'.

Signed-off-by: Dmytro Prokopchuk <dmytro_prokopchuk1@xxxxxxxx>

This patch makes MISRA Rule 5.5 "clean" for ARM only.

Was agreed to narrow deviation:
