Luis R. Rodriguez a50b22a7a1 x86/init: Disable pnpbios and rtc for X86_SUBARCH_CE4100 
As per hpa CE4100 platforms can also disable pnpbios:

  http://lkml.kernel.org/r/5702B5C2.7070101@zytor.com

Then Sebastian also recently noted that CE4100 also disables
RTC probe, to do that Sebastian had long ago added the RTC
of_have_populated_dt() check, he noted that it was meant to
skip the RTC probe on all OF platforms but as of now, CE4100
was the only x86 DT using this.

We can just fold this requirement into the platform quirk
then. This now means that all of these  match platform quirks
for pnpbios and RTC preferences:

  * X86_SUBARCH_XEN
  * X86_SUBARCH_LGUEST
  * X86_SUBARCH_INTEL_MID
  * X86_SUBARCH_CE4100
