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

Browse Source 
Since commit 0f0581b24b ("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.
