[XEN PATCH v2 3/3] eclair: 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'.
