ALSA: hda/cs35l56: Use set/get APIs to access spi->chip_select

In preparation for adding multiple CS support for a device, set/get
functions were introduces accessing spi->chip_select in
'commit 303feb3c ("spi: Add APIs in spi core to set/get
spi->chip_select and spi->cs_gpiod")'.
Replace spi->chip_select with spi_get_chipselect() API.
