staging: mt7621-pinctrl: refactor rt2880_pinctrl_dt_node_to_map function

Browse source

Using 'function' and 'group' bindings in the device tree give the
posibility of refactor 'rt2880_pinctrl_dt_node_to_map' and simplify
it a lot. Make use of 'for_each_node_with_property' function to count
number of groups for the node and iterate over the groups using
'of_property_for_each_string' calling 'pinctrl_utils_add_map_mux'
function which is the same of the custom function in this driver code
'rt2880_pinctrl_dt_subnode_to_map' which is not needed anymore.
