pinctrl: fix PINCTRL_SPPCTL=m

The PINCTRL_SPPCTL option is defined as a tristate in Kconfig, and the
help text suggests that the user can build it as a module by setting to
'm'.

However, it cannot currently be set to 'm', because SOC_SP7021, the only
platform that supports it, is a bool option that uses 'select' on it.
Also, the SP7021 requires this driver to be built in, in order to boot.

Change the tristate to bool and fix the help text.

Tested on linux-next-2026-09-14 on a LTPP3G2 board.

This impossible tristate was detected by kconfirm, a static analysis tool
for Kconfig, by Julian Braha <julianbraha@gmail.com>.
