pinctrl: Add Intel Thunder Bay pinctrl driver
About Intel Thunder Bay:
-----------------------
Intel Thunder Bay is a computer vision AI accelerator SoC based on ARM CPU.
Pinctrl IP:
----------
The SoC has a customised pinmux controller IP which controls pin
multiplexing and configuration.
Thunder Bay pinctrl IP is not based on and have nothing in common with the
existing pinctrl drivers. The registers used are incompatible with the
existing drivers, so it requires a new driver.
Add pinctrl driver to enable pin control support in the Intel Thunder Bay
SoC.
