This patch adds the basic and regulator bindings for the X-Powers AXP809
PMIC.
Also update the DC-DC converter operating frequency for AXP22X/AXP80X.

The X-Powers AXP809 is a new PMIC that is paired with Allwinner's A80
SoC, along with a slave AXP806 PMIC.
This PMIC is quite similar to the earlier AXP223, though the interrupts
and regulator have changed a bit.
This patch adds support for the interrupts and power button of the PMIC.

Switch-type regulators, such as DC1SW on AXP22X, are a secondary output
from DCDC1. They are just an on/off switch, and the driver should not
try to read its voltage directly from the DCDC1 control registers.
Instead, the core will pass down the voltage from the regulator supply
chain.

AXP20X datasheet lists the possible voltage settings for LDO4, so
it was implemented using a voltage table. Upon closer examination,
the valid voltages can be mapped into 3 linear ranges.
Move AXP20X LDO4 to use linear ranges. The supporting code can be
reused with later AXP8xx PMICs, which have a number of regulators
that have 2 linear ranges.

The X-Powers AXP809 PMIC has a similar set of regulators as the AXP221,
though a few LDOs were removed, and a new switch output added. Like the
AXP221, AXP809 also has DC1SW and DC5LDO, which are internally chained
to DCDC1 and DCDC5, respectively.
Add support for this new variant. Also remove the "axp22x_" prefix from
DC1SW/DC5LDO supply handling code, as the AXP809 uses it as well.

The AXP809 PMIC is used with the Allwinner A80 SoC, along with
an AXP806 PMIC as a slave.
This patch adds a dtsi file for all the common bindings and default
values unrelated to board design. Currently this is just listing all
the regulator nodes. The regulators are initialized based on their
device node names.

The AXP809 PMIC is the primary PMIC. It provides various supply voltages
for the SoC and other peripherals. The PMIC's interrupt line is
connected to NMI pin of the SoC.

These 3 regulators are provided in sunxi-common-regulators.dtsi.
3.0V/3.3V and 5.0V are commonly used voltages in Allwinner devices.
These dummy regulators provide a stand-in when bindings that require
one, but the real regulator is not supported yet.
Since these are no longer needed, we can disable them.
