[PATCH v1 5/6] pinctrl: spacemit: Add SPL support for K1 pinctrl driver

[Anand Moon <linux.amoon@gmail.com>]

Add `SPL_PINCTRL_SPACEMIT_K1` to enable the SpacemiT K1
pinctrl driver during SPL initialization.

Depend on `SPL_PINCTRL`, `SPL_DM`, and `PINCTRL_GENERIC`,
and select `PINCTRL_SPACEMIT_K1` to reuse the existing
driver implementation.

This allows SPL to configure pin multiplexing for early
board initialization.
