misc: 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.

ARM: qcom: silence an uninitialized variable warning

It's harmless but, if "enable" isn't set, then we pass uninitialized
values to qcom_coincell_chgr_config(). The values aren't used, but
let's silence the warning anyway.

ARM: qcom: Add coincell charger driver

This driver is used to configure the coincell charger found in
Qualcomm PMICs.

The driver allows configuring the current-limiting resistor for
the charger, as well as the voltage to apply to the coincell
(or capacitor) when charging.
