ARM: sunxi: dt: Split the SPI pinctrl groups
The pinctrl groups for SPI until now were also adding the chip selects in the SPI pinctrl group. This was causing a few issues, since a board was forced to use a random number of chipselects, even though it might use one of these chip selects for another pin. The number of chipselects defined was also not the same from one group to another because of different needs at the time these groups have been introduced, resulting in no clear view from the board DTS on what exactly is being muxed, which even might change in the future. Solve this by creating different pinctrl groups for the chipselects and the standard SPI pins (CLK, MOSI and MISO) so that we fix both issues.
