pinctrl: spacemit: move over to generic pinmux dt_node_to_map implementation

Replace the custom implementation of dt_node_to_map with
pinctrl_generic_dt_node_to_map() to demonstrate its use.
spacemit_pin_mux_config didn't provide much value in the first place,
because the group contains the information required to look up the
spacemit_pin struct corresponding to a pin, so there's no loss in
functionality as a result of the generic function carrying only the mux
data in the group's data pointer rather than having an array of
spacemit_pin_mux_config structs.

pinctrl: spacemit: k3: add initial pin support

For the pinctrl IP of SpacemiT's K3 SoC, it has different register offset
comparing with previous SoC generation, so introduce a function to do the
pin to offset mapping. Also add all the pinctrl data.

pinctrl: spacemit: enable config option

Pinctrl is an essential driver for SpacemiT's SoC,
The uart driver requires it, same as sd card driver,
so let's enable it by default for this SoC.

The CONFIG_PINCTRL_SPACEMIT_K1 isn't enabled when using
'make defconfig' to select kernel configuration options.
This result in a broken uart driver where fail at probe()
stage due to no pins found.
