I have no knowledge about multi-platform builds yet.
Currently this driver is shared between OMAP & DaVinci and both of them
doesn't exist in single image build.
There was a effort done for this SRAM Consolidation [1] but it didn't progress.
Hence I took this approach as a time-being/workaround. This was we can get
affected platforms (like AM335x) get going/working.
