[amd64] Enable CONFIG_PINCTRL_CS42L43 and CONFIG_SPI_CS42L43 explicitly
Up until v7.0-rc7 = e920c36f2073 ("ASoC: Intel: boards: fix unmet
dependency on PINCTRL") SND_SOC_INTEL_SOUNDWIRE_SOF_MACH selected
PINCTRL_CS42L43 and SPI_CS42L43. Enabled these explicitly to make sound
on (at least) Lunar Lake laptops work again.
The commit that makes this change necessary was also backported to v6.12.81~176 = 8b079642413d, so this needs backporting to 6.12. Kernels older than 6.11-rc1 (i.e. v6.11-rc1~108^2~6^2~75^2 = c073f0757663) don't have the select yet, so are not affected directly, but 6.1 has CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH=m but CONFIG_PINCTRL_CS42L43 and CONFIG_SPI_CS42L43 are disabled. So this change should probably go into 6.1, too, with a slightly different motivation though.
