On ARM systems, whether SMC or HVC instructions need to be used to issue monitor calls is typically dependent on the exception level, but there are also cases where EL1 might use SMC instructions, so there is no hard and fast rule. For ArmVirtQemu, this does depend strictly on the exception level, so set the default to HVC (for EL1 execution) and override it to SMC when booted at EL2.
