ARM: 7365/1: drop unused parameter from flush_cache_user_range

Browse source 
vma isn't used and flush_cache_user_range isn't a standard macro that
is used on several archs with the same prototype. In fact only unicore32
has a macro with the same name (with an identical implementation and no
in-tree users).

This is a part of a patch proposed by Dima Zavin (with Message-id:
[email protected]) that didn't get
accepted.
