pinctrl: madera: Add driver for Cirrus Logic Madera codecs
These codecs have a variable number of I/O lines each of which is individually selectable to a wide range of possible functions. The functionality is slightly different from the traditional muxed GPIO since most of the functions can be mapped to any pin (and even the same function to multiple pins). Most pins have a dedicated "alternate" function that is only available on that pin. The alternate functions are usually a group of signals, though it is not always necessary to enable the full group, depending on the alternate function and how it is to be used. The mapping between alternate functions and GPIO pins varies between codecs depending on the number of alternate functions and available pins.
