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 of_gpio_n_cells default is 2 when ->of_xlate() callback is
not defined. No need to assign it explicitly in the driver.

bit-mask for pins 0 to 4 is BIT(0) to BIT(4) however we ended up with BIT(n - 1)
which is not right, and this was caught by below usban check

The check with register value and mask should be & rather than &&.
While at it, also use "unsigned int" for value variable because
regmap_read() takes unsigned int *val argument.
