efi: Parse ARM error information value
ARM errors just print out the error information value, then the
value needs to be manually decoded as per the UEFI spec. Add
decoding of the ARM error information value so that the kernel
logs capture all of the valid information at first glance.
ARM error information value decoding is captured in UEFI 2.7
spec tables 263-265.
