Re: [PATCH 2/2] dt/bindings: control CS via standard GPIO operations instead of SPI-HW

From: Martin Sperl <redacted>

Change the device tree to use cs-gpios for the spi bus master
and standard gpio operation instead of relying on the HW with
just 2 chip_selects using ALT0.

This reassigns the existing CS pins 7(=CS1) and 8(=CS0)
as output instead of ALT0 (=SPI HW block controlled) 
and adds them in the list of cs-gpios for the spi-bus.
