u-boot: Add memory alignment fix for armv7 for am37x and am3517

Browse Source 
* On am335x a memory alignment issue was found when using the Linaro toolchain.
* A similar patch was applied for am335x that fixed this well documented issue.
* Add a similar fix to am37x and am3517 since this is a generic armv7 issue.

Subject: [PATCH] armv7:Unaligned access fix
This fixes an unaligned access data abort introduced when using gcc 4.7
or higher. The Linaro toolchain uses gcc 4.7.3. This is documented in u-boot
doc/README.arm-unaligned-accesses.
