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.

ARMv7-M has hardware division, so it doesn't require __div0
or any support functions for 32-bit division.

This is a preparation to introduce support for the following SoC models: S5L8720 (iPod Nano 4G, iPod Touch 2G), S5L8730 (iPod Nano 5G), S5L8723 (iPod Nano 6G) and S5L8740 (iPod Nano 7G)
The whole family consists of SoCs which are similar, running ARMv6 and Thumb2 instructions, but some peripherals are located at a different address.
No functional change is to be expected so far.

Annoyingly, this makes all of the '.S' files we compile get treated as
divided syntax, so we need to make the syntax in them explicit.

GCC 4.9 always emits assembly with divided syntax. Setting unified
syntax in inline assembly causes the assembler to complain about
GCC's generated code, because the directive extends past the scope
of the inline asm. Fix this by setting divided mode at the end of
the inline assembly block.
The assembler directives are hidden behind macros because later
versions of GCC won't need this workaround: they can be told to
use the unified syntax with -masm-syntax-unified.
