Biju Das 2e44555b05 pinctrl: mcp23s08: Simplify probe()/mcp23s08_spi_regmap_init()
Add struct mcp23s08_info and simplify probe()/mcp23s08_spi_regmap_init() by
replacing match data 'type' with 'struct mcp23s08_info'.

While at it, replace 'dev_err()'->'dev_err_probe()' and drop printing
'type' in error path for i2c_get_match_data().
