Sorry I didn't involve this earlier, but I think this is a wrong
approach, in ACPI 5.1+ spec, there is a bit in FADT table which
indicates PSCI using SMC or HVC, please see ACPI 6.2 ,
Table 5-37 Fixed ACPI Description Table ARM Boot Architecture Flags.
Can we just use that to get the conduit method for optee driver too?
