[PATCH v1 0/4] Reuse common functions from pinctrl-intel

[Raag Jadav <raag.jadav@xxxxxxxxx>]

This series exports common pinctrl functions that are used across
Intel specific platform drivers to PINCTRL_INTEL namespace and
reuses them into Baytrail, Cherryview and Lynxpoint drivers.
This helps reduce their code and memory footprint.

X86 kernels are fairly unikernels such that pinctrl-intel driver is
enabled by most Linux distributions and most Intel specific platform
drivers (inside drivers/pinctrl/intel) depend on it.

The only exception to this is Lynxpoint. But taking into account its
fairly old age, it wouldn't suffer much from pinctrl-intel dependency.
