spi: Constify spi parameters of chip select APIs

Browse Source 
commit d2f19eec510424caa55ea949f016ddabe2d8173a upstream.

The "spi" parameters of spi_get_chipselect() and spi_get_csgpiod() can
be const.

Fixes: 303feb3cc06ac066 ("spi: Add APIs in spi core to set/get spi->chip_select and spi->cs_gpiod")
