PC0~PC4 is pin group for SPI0. PA0~PA4 is pin group for SPI1.
Add device tree nodes for this groups.

Are they the only options for the muxing of the SPI pins? if so, you'd
need to remove the pin bank, and to set the pinctrl-0 and
pinctrl-names in the DTSI.

We also move the CS pin out in a separate group to accomodate devices
that use a GPIO instead.
