[PATCH v2 3/5] ARM: omap3: Remove hand-encoded SMC instructions

[Dave Martin]

For various reasons, Linux now only officially supports being built
with tools which are new enough to understand the SMC instruction.

Replacing the hand-encoded instructions when the mnemonic also
allows for correct assembly in Thumb-2 (otherwise, the result is
random data in the middle of the code).

The Makefile already ensures that this file is built with a high
enough gcc -march= flag (armv7-a).
