ARM: 5757/1: Thumb-2: Correct "mov.w pc, lr" instruction which is unpredictable

The 32-bit wide variant of "mov pc, reg" in Thumb-2 is unpredictable
causing improper handling of the undefined instructions not caught by
the kernel. This patch adds a movw_pc macro for such situations
(currently only used in call_fpe).
