Input: Explicitly include correct DT includes

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

Input: sun4i-lradc-keys - add support for R329 and D1

This LRADC variant uses the same 3/4*AVCC reference voltage as the A83T
variant. The R329 and D1 LRADCs appear to be identical, so D1 support is
accomplished through having the R329 LRADC as a fallback compatible.

Input: sun4i-lradc-keys - add optional clock/reset support

Until the R329, the LRADC hardware was always active. Now it requires
enabling a clock gate and deasserting a reset line. Add support for this
variant of the hardware.

Input: sun4i-lradc-keys - add wakeup support

Allow the driver to wake the system on key press if the "wakeup-source"
property is provided in the device tree. Using the LRADC as a wakeup
source requires keeping the AVCC domain active during sleep. Since this
has a nontrivial impact on power consumption (sometimes doubling it),
disable the LRADC wakeup source by default.

Input: sun4i-lradc-keys - add of_node_put() before return

Each iteration of for_each_child_of_node puts the previous
node, but in the case of a return from the middle of the loop, there is
no put, thus causing a memory leak. Hence add an of_node_put before the
return in three places.
Issue found with Coccinelle.

Input: sun4i-a10-lradc-keys - add support for A83T

Allwinner A83T SoC has a low res adc like the one in Allwinner A10 SoC,
however, the A10 SoC's vref of lradc internally is divided by 2/3 and
the A83T SoC's vref of lradc internally is divided by 3/4, thus add
a hardware variant for it to be compatible with various devices.

Input: add new sun4i-lradc-keys driver

Allwinnner sunxi SoCs have a low resolution adc (called lradc) which is
specifically designed to have various (tablet) keys (ie home, back, search,
etc). attached to it using a resistor network. This adds a driver for this.

There are 2 channels, currently this driver only supports chan0 since there
are no boards known to use chan1.

This has been tested on an olimex a10s-olinuxino-micro, a13-olinuxino, and
a20-olinuxino-micro.
