Thumb-2: Add some .align statements to the .S files
Since the Thumb-2 instructions can be 16-bit wide, data in the .text sections may not be aligned to a 32-bit word and this leads to unaligned exceptions. This patch does not affect the ARM code generation. Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
