[PATCH v3] pinctrl: spacemit: enable config option

[Yixun Lan]

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.

This should fix problem that CONFIG_PINCTRL_SPACEMIT_K1 is not enabled
when using make defconfig, thus fail to initilize uart driver which requst
pins during probe stage.

Changes in v3:
- switch PINCTRL_SPACEMIT_K1 from tristate to bool
- Link to v2: https://lore.kernel.org/r/20250212-k1-pinctrl-option-v2-1-bde7da0bc0d9@gentoo.org

Changes in v2:
- set default as y
- Link to v1: https://lore.kernel.org/r/20250207-k1-pinctrl-option-v1-1-e8a7e4d8404f@gentoo.org
