The Banana Pro has an AMPAK AP6181 WiFi+Bluetooth module. The WiFi part
is a BCM43362 IC connected to MMC3 of the A20 SoC via SDIO. The IC also
takes a power enable signal via GPIO.

This commit adds a device-tree node to power it up, so the mmc subsys
can scan it, and enables the mmc controller which is connected to it.

As the wifi enable pin of the AP6181 module is not really a regulator,
switch the mmc3 node to the mmc-pwrseq framework for controlling it.
This more accurately reflectes how the hardware actually works.

In the past, all the MMC pins had

	allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;

which was actually a no-op. We were relying on U-boot to set the bias
pull up for us. These properties were removed as part of the fix up to
actually support no bias on the pins. During the transition some boards
experienced regular MMC time-outs during normal operation, while others
completely failed to initialize the SD card.

Given that MMC starts in open-drain mode and the pull-ups are required,
it's best to enable it for all the pin settings.

I am getting the following warning when I build kernel 4.9-git on my
PowerBook G4 with a 32-bit PPC processor:

    AS      arch/powerpc/kernel/misc_32.o
  arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef]

This problem is evident after commit 989cea5c ("kbuild: prevent
lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an
error that has been in the code since 2005 when this source file was
created.  That was with commit 9994a338 ("powerpc: Introduce
entry_{32,64}.S, misc_{32,64}.S, systbl.S").

The offending line does not make a lot of sense.  This error does not
seem to cause any errors in the executable, thus I am not recommending
that it be applied to any stable versions.

Thanks to Nicholas Piggin for suggesting this solution.

The timer type simplifications caused a new gcc warning:

     elapsed_ns = ktime_to_ns(ktime_sub(ktime_get(), time_start));

despite the actual use of "time_start" not having changed in any way.
It appears that simply changing the type of ktime_t from a union to a
plain scalar type made gcc check the use.

The variable wasn't actually used uninitialized, but gcc apparently
failed to notice that the conditional around the use was exactly the
same as the conditional around the initialization of that variable.

Add an unnecessary initialization just to shut up the compiler.

Pull timer type cleanups from Thomas Gleixner:
 "This series does a tree wide cleanup of types related to
  timers/timekeeping.

   - Get rid of cycles_t and use a plain u64. The type is not really
     helpful and caused more confusion than clarity

   - Get rid of the ktime union. The union has become useless as we use
     the scalar nanoseconds storage unconditionally now. The 32bit
     timespec alike storage got removed due to the Y2038 limitations
     some time ago.

     That leaves the odd union access around for no reason. Clean it up.
