The original arm_event trace code only traces out ARM processor
error information data. According to UEFI_2_8_A_Feb14 specification
chapter N2.4.4, the ARM processor error section includes several
ARM processor error information, several ARM processor
context information and several vendor specific error
information structures.
Add code to trace out all ARM processor context information and
vendor specific error information with raw hex format.
