ARM: 6412/1: kprobes-decode: add support for MOVW instruction

Browse source

The MOVW instruction moves a 16-bit immediate into the bottom halfword
of the destination register.

This patch ensures that kprobes leaves the 16-bit immediate intact, rather
than assume a 12-bit immediate and mask out the upper 4 bits.
