pinctrl: imx: use generic pinmux helpers for managing functions

Browse Source 
Now using function_desc structure instead of imx_pmx_func.

Also leveraging generic functions to retrieve functions count/name/groups.

The imx_free_funcs function can be removed since it is now handled by
the core driver during unregister.
