Subject: [PATCH v1 2/2] ALSA: hda: cs35l41: Only add SPI CS GPIO if SPI is enabled in kernel

If CONFIG_SPI is not set in the kernel, there is no point in trying
to set the chip selects. We can selectively compile it.

Fixes: 8c4c216db8fb ("ALSA: hda: cs35l41: Add config table to support many laptops without _DSD")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202312192256.lJelQEoZ-lkp@intel.com/
