[U-Boot] [PATCH v3 1/6] arm: adapt asm/linkage.h from Linux

This will add ARM specific over-rides for the defines
from linux/linkage.h

Signed-off-by: Aneesh V <aneesh at ti.com>

Not adding the defines for __ALIGN and __ALIGN_STR
because it's not clear why alignment is set to 0
(single byte alignment).

Creates a checkpatch error that can not be avoided

Changes in V2:
 - Newly added
