ipq806x: chromium: Support Chromium "crossystem" GPIO tooling
ChromiumOS's vboot_reference tooling [1] provides convenient access to
various firmware and hardware details via its `crossystem` tool.
crossystem currently:
(1) relies on the v1 GPIO cdev API to read GPIOs; and
(2) expects gpio-line-names properties.
Enable the kernel config, and document a few pins for OnHub devices.
I only go so far as to pull two relevant names out of the vendor device
tree. Others could perhaps be backfilled if the info is available and
useful.
