pinctrl: sophgo: introduce generic probe function

Since different series of the Sophgo chip share a common pinctrl data
structure. It is necessary to add a common probe function to alloc
the this data structure. Add pctrl_init callback to allow soc to perform
its own initialization.

pinctrl: sophgo: avoid to modify untouched bit when setting cv1800 pinconf

When setting pinconf configuration for cv1800 SoC, the driver just writes
the value. It may zero some bits of the pinconf register and cause some
unexpected error. Add a mask to avoid this.
