[PATCH] xen/char: mvebu-uart: Fix MISRA C 2012 Rule 20.7 violation

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

The macro parameters 'off' and 'uart' are used as expressions and it is
good to be enclosed in parentheses to prevent against unintended expansion.

For the 'uart' case, in mvebu3700_write(), correct the second parentheses
that seems to have been accidently misplaced.
