[PATCH] firmware: fix alignment of firmware images

[Ahmad Fatoum]

ASM_LGPTR is a preprocessor symbol, not a Make variable, so expanding it
in the Makefile results in .p2align without an argument, which disables
alignment requirement. Fix this to restore the sizeof(void *) alignment
we had before.

Fixes: a59e2740b4a7 ("firmware: reference pointer alignment defined in <asm-generic/pointer.h>")
