While the SinA31s does have a proper 5-pin mini USB OTG port, the ID
pin does not seem to work. The pin used in the schematics is always low,
regardless of the attached OTG cable or SoC internal pin bias settings.

The v1.5 board is missing bias resistors shown in the schematics for
earlier revisions, and the connections of the remaining one does not
match the schematics either.

In addition, VBUS for this port is disconnected from the board's 5V
power rail. The board features a pad to solder jumper pins to connect
VBUS to 5V manually.

Given the above and the fact that the board has 5 more USB host ports,
it makes more sense to have the OTG port work in peripheral mode.

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.
