ARM: 6655/1: Correct WFE() in asm/spinlock.h for Thumb-2
ARM: 6655/1: Correct WFE() in asm/spinlock.h for Thumb-2

The content for ALT_SMP() in the definition of WFE() expands to 6
bytes (IT cc ; WFEcc.W), which breaks the assumptions of the fixup
code, leading to lockups when the affected code gets run.

This patch works around the problem by explicitly using an
IT + WFEcc.N pair.
