Hello,

I noticed that EFI RTC was disabled on X86 really long time ago due to
Intel reference firmwares coming with broken EFI.

I edited the Kconfig to enable it, and see how it works on my laptop
(AMD HX370). I can confirm that it boots well. I have not done any
more extensive tests than that.

What do you think about re-enabling EFI RTC behind some expert config
flag, and ask more people to test it on modern X86 hardware?

I don't mind do that, I believe the issue is that this is going to break
the users that have a broken EFI and rely on CMOS. Please copy the x86
maintainers on your patch.
