libpayload: ARM: Keep track of the CPSR when exceptions happen.
Use the SPSR to extract and inject CPSR values when an exception happens and
pass that information to exception hooks.
The register structure GDB expects when using its remote protocol has a spot
for the CPSR.
BUG=None
TEST=Built and booted on link, nyan.
BRANCH=None
