arm64: fixmap: fix missing sub-page offset for earlyprintk

Commit d57c33c5daa4 (add generic fixmap.h) added (among other
similar things) set_fixmap_io to deal with early ioremap of devices.

More recently, commit bf4b558eba92 (arm64: add early_ioremap support)
converted the arm64 earlyprintk to use set_fixmap_io. A side effect of
this conversion is that my virtual machines have stopped booting when
I pass "earlyprintk=uart8250-8bit,0x3f8" to the guest kernel.

Turns out that the new earlyprintk code doesn't care at all about
sub-page offsets, and just assumes that the earlyprintk device will
be page-aligned. Obviously, that doesn't play well with the above example.

Further investigation shows that set_fixmap_io uses __set_fixmap instead
of __set_fixmap_offset. A fix is to introduce a set_fixmap_offset_io that
uses the latter, and to remove the superflous call to fix_to_virt
(which only returns the value that set_fixmap_io has already given us).

With this applied, my VMs are back in business. Tested on a Cortex-A57
platform with kvmtool as platform emulation.

Pull ACPI and power management fixes from Rafael Wysocki:
 "A bunch of regression fixes this time.  They fix two regressions in
  the PNP subsystem, one in the ACPI processor driver and one in the
  ACPI EC driver, four cpufreq driver regressions and an unrelated bug
  in one of the drivers.  The regressions are recent or introduced in
  3.14.

  Specifics:

   - There are two bugs in the ACPI PNP core that cause errors to be
     returned if optional ACPI methods are not present.  After an ACPI
     core change made in 3.14 one of those errors leads to serial port
     suspend failures on some systems.  Fix from Rafael J Wysocki.

   - A recently added PNP quirk related to Intel chipsets intorduced a
     build error in unusual configurations (PNP without PCI).  Fix from
     Bjorn Helgaas.

   - An ACPI EC workaround related to system suspend on Samsung machines
     added in 3.14 introduced a race causing some valid EC events to be
     discarded.  Fix from Kieran Clancy.

   - The acpi-cpufreq driver fails to load on some systems after a 3.14
     commit related to APIC ID parsing that overlooked one corner case.
     Fix from Lan Tianyu.

   - Fix for a recently introduced build problem in the ppc-corenet
     cpufreq driver from Tim Gardner.

   - A recent cpufreq core change to ensure serialization of frequency
     transitions for drivers with a ->target_index() callback overlooked
     the fact that some of those drivers had been doing operations
     introduced by it into the core already by themselves.  That
     resulted in a mess in which the core and the drivers try to do the
     same thing and block each other which leads to deadlocks.  Fixes
     for the powernow-k7, powernow-k6, and longhaul cpufreq drivers from
     Srivatsa S Bhat.

   - Fix for a computational error in the powernow-k6 cpufreq driver
     from Srivatsa S Bhat"
