The Ingenic JZ4760 and JZ4770 both have an extra DMA core named BDMA
dedicated to the NAND and BCH controller, but which can also do
memory-to-memory transfers. The JZ4760 additionally has a DMA core named
MDMA dedicated to memory-to-memory transfers. The programming manual for
the JZ4770 does have a bit for a MDMA clock, but does not seem to have
the hardware wired in.
Add macros for the MDMA and BDMA clocks to the dt-bindings include
files, so that they can be used within Device Tree files.
