Use the new tick_suspend/resume_local() and get rid of the
homebrewn implementation of these in the ARM bL switcher.  The
check for the cpumask is completely pointless.  There is no harm
to suspend a per cpu tick device unconditionally.  If that's a
real issue then we fix it proper at the core level and not with
some completely undocumented hacks in some random core code.

Move the tick internals to the core code, now that this nuisance
is gone.

Xen calls on every cpu into tick_resume() which is just wrong.
tick_resume() is for the syscore global suspend/resume
invocation. What XEN really wants is a per cpu local resume
function.

Provide a tick_resume_local() function and use it in XEN.

Also provide a complementary tick_suspend_local() and modify
tick_unfreeze() and tick_freeze(), respectively, to use the
new local tick resume/suspend functions.

clockevents_notify() is a leftover from the early design of the
clockevents facility. It's really not a notification mechanism,
it's a multiplex call.

We are way better off to have explicit calls instead of this
monstrosity. Split out the suspend/resume() calls and invoke
them directly from the call sites.

No locking required at this point because these calls happen
with interrupts disabled and a single cpu online.

The parent clock of the sun5i timer is the AHB clock, which rate
might change because of other devices requirements.

This is for example the case on the Allwinner A31, where the DMA
controller needs a minimum rate higher than the default, that is
enforced after the timer driver has probed.

Add clock notifiers to make sure we reflect the clock rate
changes in the timer rates.

has been probed already, but also when it has no corresponding

The dw_apb_timer_of timer is using __raw_readl() to access the
timer register, which is causing issues when the system is
running in big endian mode. Fix this by using readl_relaxed()
which should account for the endian settings.

This fixes issues where the time jumps around in the dmesg
output due to returnling __le32 values.

For an example, these two console lines show time running
backwards:

 "The latest and greatest fixes for ARM platform code.  Worth pointing
  out are:

   - Lines-wise, largest is a PXA fix for dealing with interrupts on DT
     that was quite broken.  It's still newish code so while we could
     have held this off, it seemed appropriate to include now

   - Some GPIO fixes for OMAP platforms added a few lines.  This was
     also fixes for code recently added (this release).

   - Small OMAP timer fix to behave better with partially upstreamed
     platforms, which is quite welcome.

   - Allwinner fixes about operating point control, reducing
     overclocking in some cases for better stability.

  plus a handful of other smaller fixes across the map"
