spi: spi-fsl-dspi: Use max_native_cs instead of num_chipselect to set SPI_MCR

Browse source

[ Upstream commit 2c2b3ad2c4 ]

If cs-gpios property is used in devicetree then ctlr->num_chipselect value
may be changed by spi_get_gpio_descs().
So use ctlr->max_native_cs instead of ctlr->num_chipselect to set SPI_MCR

Fixes: 4fcc7c2292 (spi: spi-fsl-dspi: Don't access reserved fields in SPI_MCR)
