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.

The MAX8903 uses up to 5 different GPIO lines to control and
monitor charging.
When converting to use GPIO descriptors instead of the old
GPIO numbers the following side-refactorings were done:
- Decomission the platform data container struct as all
GPIO descriptors are now "live" members of the driver
state container. The "dc_valid" and "usb_valid" just
indicate the presence of a DC or USB charger detection
line, and this can be handled by just checking if
the optional GPIO descriptor for each is != NULL.
- The gpiolib will now respect the GPIO_ACTIVE_LOW flag
for each of the lines, meaning gpiod_get_value() for example
will return 1 (asserted) if a line is flagged as
active low and is also physically low. The same applies
to output lines, vice versa mutatis mutandis. The code
has been augmented to account for this in all sites.
- The terse parenthesis such as this:
gpio_set_value(pdata->cen, ta_in ? 0 :
(data->usb_in ? 0 : 1));
have been expanded to more readable if / else if / else
statements that are easier for humans to read.
- Comments were inserted to underscore polarity in each
case where it could be confusing to users of the old code.
One thing is notable: the device tree bindings does not show
an example of polarity assigned for the line "dcm-gpios"
DC current monitor, is assumed to be flagged GPIO_ACTIVE_HIGH
and driving it high (asserted) will achieve DC charger current
limits and driving it low will achieve USB charger current
limits. Device trees with this (optional) GPIO line defined
should definately be flagged as GPIO_ACTIVE_HIGH.

The platform data header is not included by any other file in
the kernel but the driver itself. Decomission the stand-alone
header and absorb it into the driver itself.

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.
