All normal memory areas should be mapped as such. We added these un-cached holes in our memory map to hack around the remoteproc driver missing the proper cache maintenance operations. The problem is having these non-cached memory map areas causes stability issues later in system operation due to the nature of the K3 coherency architecture. Plus these are board specific carveouts and instead should have been added at the board level, not here in the SoC common code area. Remove these non-cached memory map areas.
