From: Mark Salter <msalter@xxxxxxxxxx>
Subject: rtc-ia64-allow-other-architectures-to-use-efi-rtc-v2
This is v2 of the patch to fix a boot problem with kernels building in
rtc-efi but not being booted via EFI. In that case, runtime services are
not available so there is no point in registering the platform device.
