[PATCH v2 0/2] uefi: fix fwts_uefi_rt_support_status_get()

[Heinrich Schuchardt]

The UEFI 2.8 Errata A specification has clarified that
RuntimeServicesSupported is not a UEFI variable but a value in the
EFI_RT_PROPERTIES_TABLE configuration table. Since Linux 5.11 the value can
be retrieved via an IOCTL call.

Replace the code trying to read the non-existent RuntimeServicesSupported
variable by the IOCTL call.

If RuntimeServicesSupported == 0, no runtime service is supported.

Test results for current U-Boot with and without the IOCTL ares available
as:

https://github.com/U-Boot-EFI/u-boot-fwts-results/blob/master/results-without-ioctl.log

v2:
	correct status tests
