ARM: 8828/1: uaccess: use unified assembler language syntax
Convert the conditional infix to a postfix to make sure this inline
assembly is unified syntax. Since gcc assumes non-unified syntax
when emitting ARM instructions, make sure to define the syntax as
unified.
This allows to use LLVM's integrated assembler.
