Subject: [PATCH 3/3] spi: spi-microchip-core: Fix the number of chip selects supported

The SPI controller in PolarFire SoC has multiple chip selects, but only
one is wired up in the MSS. Therefore, fix the driver to chose one
chip select.

Fixes: 9ac8d17694b6 ("spi: add support for microchip fpga spi controllers")
