powerpc/devicetrees: Change 'gpios' to 'cs-gpios' on fsl, spi nodes 



Since commit 0f0581b2 ("spi: fsl: Convert to use CS GPIO
descriptors"), the prefered way to define chipselect GPIOs is using
'cs-gpios' property instead of the legacy 'gpios' property.

- clock-frequency : input clock frequency to non FSL_SOC cores



Optional properties:

- gpios : specifies the gpio pins to be used for chipselects.

- cs-gpios : specifies the gpio pins to be used for chipselects.

  The gpios will be referred to as reg = <index> in the SPI child nodes.

  If unspecified, a single SPI device without a chip select can be used.

- fsl,spisel_boot : for the MPC8306 and MPC8309, specifies that the

  SPISEL_BOOT signal is used as chip select for a slave device. Use

  reg = <number of gpios> in the corresponding child node, i.e. 0 if

  the gpios property is not present.

  the cs-gpios property is not present.
