This switches the babbage board to probe from devicetree for all
for all devices we currently support probing from devicetree.

The mc13892 driver knows that it needs spi-cs-high, so the mc13892
will work. The dataflash also connected to this bus though can only
be probed when the mc13892 is inactive. Due to driver probe differences
we can only make sure the mc13892 is inactive when we put the information
into the devicetree.
