Add initial support for DA8xx SoC's and the spectrum digital DA830 EVM board.
DA8xx is similar to DaVinci devices, but has a differing memory map and updated peripherals. It is intended that DaVinci drivers will be modified in some way to support these differences.
A side effect of this is that there are some legacy code constructs in this patch set that are required to utilise the DaVinci drivers as they stand now. For example there are some volatiles and memory pointer types defined that are no longer considered acceptable.
The new code in this patch set doesn't use these constructs and the remaining artifacts can be removed when the DaVinci drivers stop using them.
--- Changes from previous patch set:
Removed Ethernet support (will add after davinci_emac has been patched) Moved board support to DaVinci directory for easier driver integration. Patch set run through checkpatch. (remaining WARNINGS should be justifiable) Removed unused code. Addressed comments on v1 Patch set.
