libpayload: ARM: Don't leave alignment checking on after the exception test
Currently, the exception handling code on ARM in libpayload turns on alignment
checks as an easy way to generate an exception for testing purposes. It was
leaving it on which disabled unaligned accesses for other, unlreated code
running later. This change adjusts the code so the original value of the
alignment bit is restored after the test exception.
Built and booted into depthcharge on pit with an unaligned accesses added
after the call to exception_init in the depthcharge's main. Before this
change, the access caused an exception. After this change, the access
completed successfully.
