defaultenv: Align defaultenv array
The default environment buffer is an unsigned char array and thus may be unaligned. Some decompression algorithms expect the buffer to be sufficiently aligned for u32 accesses. We make this sure by copying the default env to a temporary buffer. Instead of doing this just add a __aligned(4) to the default environment. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
