Add support for requesting GPIOs with a live device tree.
This involves adjusting the function signature for the legacy function
gpio_request_by_name_nodev(), so fix up all callers.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

This driver implements SPI protocol in master mode to communicate
with the SPI device connected on SPI bus. It handles /CS explicitly
by controlling respective pin as gpio ('cs-gpios' property in dt node)
and uses PIO mode for SPI transaction. It is configurable based
on driver-model only.
