dt-bindings: lcdif: Document the dmas/dma-names properties 



i.MX28 has an RX DMA channel associated with the LCDIF controller.

Document the 'dmas' and 'dma-names' properties to fix the following
dt-schema warnings:

lcdif@80030000: 'dma-names', 'dmas' do not match any of the regexes: 'pinctrl-[0-9]+'
