This custom property does not seem to be needed as the number of chip
selects can be parsed from the devicetree file directly.

We got rid of "fsl,spi-num-chipselects" property in the spi-imx driver
in this commit:

commit b36581df7e788b674a4efbb8da7fe4a00c207e8b

spi: imx: Using existing properties for chipselects

Patch reuse existing "chip_select" and "cs_gpio(s)" fields from SPI core.

and we should try to also avoid such property in spi-fsl-lpspi as well.
