Merge tag 'intel-pinctrl-v4.21-1' of git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into devel

intel-pinctrl for v4.21-1

Switch to generic ->probe() callbacks.
Simplify getting .driver_data.
Code formatting fixes and headers clean up.

Special case is the driver for Intel Cherryview SoC, where GPIO enabling bit
was mistakenly cleared when pin gets freed. It's fixed now.

The below commit went to v4.20-rc3, that's why duplication.
