Enable reading tx and rx buswidth from DT via spi-uclass. To get these from uclass spi-flash compatible string has to be added to flash node.

This chip is on the board but handling should be done via firmware not via Linux driver. Changing status property to keep it in the tree to describe it instead of removing this node completely.

If there are more instances of si570 clock-output-names property should be used for differentiation of clock output. The patch is adding this optional properties for all zynqmp boards with si570 chip.
