arm: armv7: add compile option -mno-unaligned-access if available

Recent compiler generates unaligned memory access in armv7 default.
But current U-Boot does not allow unaligned memory access, so it causes
data abort exception.
This patch add compile option "-mno-unaligned-access" if it is available.
