[PATCH 2/4] dt-bindings: iio: light: sharp,gp2ap020a00f: Add GP2AP030A00F

[Linus Walleij <linusw@kernel.org>]

The GP2AP030A00F uses the same register address layout and interrupt
interface as the GP2AP020A00F, but returns raw clear and infrared counts
instead of providing automatic illuminance calculation. Describe it in
the existing binding with its own compatible.

Keep the core and I/O pull-up supplies optional so boards with hardwired
power do not have to describe them.
