pinctrl: mediatek: common-v1: Use common probe function

Most of the mediatek pinctrl drivers are calling mtk_pctrl_init() and
passing only a pointer to struct mtk_pinctrl_devdata, as the regmap
handle it passed from device-tree, with the exception of mt6397.

For all of the drivers that don't require passing a struct regmap
pointer from a parent device, simplify the probe mechanism by assigning
the required structure as match data and use mtk_pctrl_common_probe()
as their probe function.

While at it, also collapse the of_device_id entries to a single line,
as they all fit in max 83 columns, which is acceptable.
