ARM: platform fixups: remove mdesc argument to fixup function
Get rid of the mdesc pointer in the fixup function call. No one uses
the mdesc pointer, it shouldn't be modified anyway, and we can't wrap
it, so let's remove it.
Platform files found by:
$ regexp=$(git grep -h '\.fixup.*=' arch/arm |
sed 's!.*= *\([^,]*\),* *!\1!' | sort -u |
tr '\n' '|' | sed 's,|$,,;s,|,\\|,g')
$ git grep $regexp arch/arm
