[Patch ARM] Fix thinko in use of TARGET_UNIFIED_ASM

[Ramana Radhakrishnan]

While paving the way to turn on unified syntax in ARM state I came 
across this use of TARGET_UNIFIED_ASM that really doesn't make sense.

The idea that pop has different encoding sizes is a property of the 
Thumb instruction set rather than a property of which form of unified 
syntax was used. I still have quite a large patch set for the unified 
asm switch but it seems useful to get this one out of the way to catch 
any other issues.

Tested with an appropriate set of multilibs on arm-none-eabi / applied. 
Bootstrapped on armhf.

Applied to trunk.

Ramana
