This series converts the TI DaVinci/Keystone SPI controller device tree
bindings from the legacy text format to DT schema.
- Patch 1 renames property ti,davinci-spi-num-cs from keystone-k2l.dtsi,
as the driver uses the standard num-cs property.
- Patch 2 Converts ti,davinci-spi from text to DT schema.

Changes in v3:
- patch 2: since old text binding required num-cs, #address-cells, and
#size-cells mark them as required
- patch 2: davinci-spi don't work as spi-slave i.e address-cells 0 is
not applicable and spi-controller permits both 0 and 1 so explicitely
define #address-cells as 1

limits
