pinctrl: sh-pfc: pfc-r8a7790: Reorganize VIN0 data pins
This reorganizes and renames VIN0 data pin groups to cover all possible configurations. There's total of eight data pin groups, one per each configuration. Most of the groups share the same pin/mux array. Only the 18-bit configuration needs a separate pin/mux array since in combines interleaved data pins.
