The SPI "hard" controller in PolarFire SoC has eight CS lines, but only
one CS line is wired. When the 'num-cs' property is not specified in
the device tree, the driver defaults to the MAX_CS value, which has
been fixed to 1 to match the hardware configuration; however, when the
'num-cs' property is explicitly defined in the device tree, it
overrides the default value.
