Subject: [PATCH 3/3] pinctrl: sx150x: add a static gpio/pinctrl pin range mapping

Without such a range, gpiolib fails with -EPROBE_DEFER, pending the
addition of the range. So, without a range, gpiolib will keep
deferring indefinitely.

Fixes: e10f72bf4b3e ("gpio: gpiolib: Generalise state persistence beyond sleep")
