Add the regulators for each bank on this boards.
For VCC-PL only add a comment on what regulator is used. We cannot add
the property without causing a circular dependency as the PL pins are
used to talk to the PMIC.

Allwinner A64 SoC has separate supplies for PC, PD, PE, PG and PL. This
patch adds regulators for them to the pinctrl node.
Exception is PL which is used by the RSB bus. To avoid circular
dependencies, VCC-PL is omitted.
On boards with eMMC, VCC-PC is supplied by ELDO1, instead of DCDC1.

A64-OLinuXino uses DCDC1 (VCC-IO) for MMC1 supply. In commit 916b68cfe4
("arm64: dts: a64-olinuxino: Enable RTL8723BS WiFi") ALDO2 is set, which is
VCC-PL. Since DCDC1 is always present, the boards are working without a
problem.
This patch sets the correct regulator.

On these A64 devices, the DC input jacks are wired to the ACIN pins of
the PMIC, which is represented by the AC power supply. With the
exception of the Nanopi A64, all devices include LiPo batteries or have
connectors for them, which are represented by the battery power supply.
Enable these power supplies in the device tree.

The PHY found on the A64-OLinuXino requires a TX delay in order to
operate properly. Olimex uses a 600ps second delay in their BSP, and
that has been found to work, so let's use that value in the current
DT.

The pinmux name and label for a specific function should denote which
pingroup it is on, or if there is only one option for the function, have
not enumerating prefix/suffix at all.
The "uart0_pins_a" label is renamed to "uart0_pb_pins" to fit our
current style. The node name "uart0" is also changed to "uart0-pb-pins"
to match.

The Olinuxino has two USB sockets:
USB0 is connected to a micro B socket. As it has the ID pin wired and
the VBUS line connected to the PMIC, we describe it as a proper OTG socket,
which switches between host and device automatically.
USB1 is connected to a normal USB A socket. PG9 enables the power line,
so add the required regulator as well.

The Olinuxino board uses DDR3L chips which are supposed to be driven
with 1.35V. The reset default of the AXP is properly set to 1.36V.
While technically the chips can also run at 1.5 volts, changing the
voltage on the fly while booting Linux is asking for trouble. Also
running at a lower voltage saves power.
So fix the DCDC5 value to match the actual board design.

On usual A64 board design the power of HDMI controller is connected to
DLDO1 of the AXP803 PMIC. If this regulator is shut down, the HDMI
output will be blank. Therefore the simplefb driver should keep this
regulator on.
Add the regulator to all currently available A64 boards' simplefb_hdmi
device node, if the board is capable of outputing HDMI.

Using the cd-inverted property is not useful when GPIOs are used as card
detects since the polarity can be specified with the usual
GPIO_ACTIVE_(HIGH|LOW) GPIO flags. It has also caused confusion for
U-Boot developers, so migrate all sunxi boards away from cd-inverted.
