spi: fsl-lpspi: fix only one cs-gpio working

[ Upstream commit bc3a8b295e5bca9d1ec2622a6ba38289f9fd3d8a ]

Why it does not work at the moment:
- num_chipselect sets the number of cs-gpios that are in the DT.
  This comes from drivers/spi/spi.c
- num_chipselect gets set with devm_spi_register_controller, that is
  called in drivers/spi/spi.c
- devm_spi_register_controller got called after num_chipselect has
  been used.

How this commit fixes the issue:
- devm_spi_register_controller gets called before num_chipselect is
  being used.
