Subject: [PATCH 2/2] arm64: to allow EFI_RTC can be selected on ARM64

Now, ARM64 is also support EFI startup. We hope use EFI runtime services
to get/set current time and date.

RTC_LIB only controls some configs in drivers/char/Kconfig(included
EFI_RTC), and will be automatically selected when RTC_CLASS opened. So
this patch have no functional change but give an opportunity to select
EFI_RTC when RTC_CLASS closed.
