[PATCH 7/8] ARM: shmobile: r8a7790: add dmac0 dmac1 nodes

[Ben Dooks <ben.dooks@codethink.co.uk>]

Add nodes for the SYS-DMA controllers, SYS-DMAC0 and SYS-DMAC1. These
both share the same device sources, so are wrapped in the shdma-mux
node to allow both to be used.

Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk>

---
v2:
	- fix indentation
	- remove extra channel on dmac1
v3:
	- fix issues with naming in dt
	- remove mapping of chcr data, will be in driver
