rtc test failed on Oracle ARM64 baremetal Standard.A1.160

Issue found on:
  * B-oracle-5.4
  * F-oracle-5.4
  * J-oracle-5.15

This issue does not exist with:
  * F-oracle-5.15

This instance was not tested with B-oracle-4.15

Test failed because /dev/rtc0 does not exist:
  TestNAError: RTC device /dev/rtc0 does not exist
  TEST_NA rtc rtc timestamp=1654113493 localtime=Jun 01 19:58:13 RTC device /dev/rtc0 does not exist

The rtc test is failing constantly since F-oracle-5.15.0-1016 on this node, bug 1987831

Also, I noticed that CONFIG_RTC_DRV_EFI is set to y on F-oracle-5.15
$ grep CONFIG_RTC_DRV_EFI /boot/config-5.15.0-101*
/boot/config-5.15.0-1013-oracle:CONFIG_RTC_DRV_EFI=y
/boot/config-5.15.0-1015-oracle:CONFIG_RTC_DRV_EFI=y
/boot/config-5.15.0-1016-oracle:CONFIG_RTC_DRV_EFI=y

Maybe this is why this test is not working on other kernels.
