spi: reduce device chip select limit again

The spi chipselect limit SPI_CS_CNT_MAX was raised with commit
2f8c7c3715 ("spi: Raise limit on number of chip selects") from 4 to 16
to accommodate spi controllers with more than 4 chip selects, and then
later to 24 with commit 96893cdd47 ("spi: Raise limit on number of
chip selects to 24").

Now that we removed SPI_CS_CNT_MAX limiting the chip selects of
controllers, we can reduce the amount of chip selects per device again
to 4, the original value.
