[PATCH 1/7] xen/arm: gic_v3_its: Fix MISRA C 2012 Rule 20.7 violations

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

In macros GITS_TYPER_DEVICE_ID_BITS(), GITS_TYPER_EVENT_ID_BITS() and
GITS_BASER_ENTRY_SIZE(), add parentheses around the macro parameter to
prevent against unintended expansions.
Realign subsequent lines, if any.
