ALSA: hda: cs35l41: fix building without CONFIG_SPI
When CONFIG_SPI is disabled, the driver produces unused-variable warning:
sound/pci/hda/cs35l41_hda_property.c: In function 'generic_dsd_config':
sound/pci/hda/cs35l41_hda_property.c:181:28: error: unused variable 'spi' [-Werror=unused-variable]
181 | struct spi_device *spi;
| ^~~
sound/pci/hda/cs35l41_hda_property.c:180:27: error: unused variable 'cs_gpiod' [-Werror=unused-variable]
180 | struct gpio_desc *cs_gpiod;
| ^~~~~~~~
Avoid these by turning the preprocessor contionals into equivalent C code,
which also helps readability.
