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.
