[PATCH v1 0/3] Introduce Intel Tangier pinctrl driver

[Raag Jadav <raag.jadav@intel.com>]

Merrifield and Moorefield pinctrl driver implementations are similar
in terms of how they access the hardware. We can consolidate their
pinctrl functionalities into a common library driver.

This patch set introduces:

1. Intel Tangier driver that supports the common pinctrl functionalities
   for Merrifield and Moorefield platforms.

2. Intel Tangier adaptation for Merrifield pinctrl driver.

3. Intel Tangier adaptation for Moorefield pinctrl driver.

Tested on Intel Edison platform.
No deviation observed in the contents of below entries before and after
this patchset.
