arm: enable unified assembly syntax in more files

This makes these files compileable, or in some cases less
broken, on Cortex-M targets.

In lcd-16bit.c, newer versions of GAS complain about the
infix condition codes so we use the suffix form instead,
which requires unified syntax to compile on GCC 4.9.
