Log message:
uncached_base was introduced early in IP27 support, since these designs use
subspaces in the CCA_NC uncached memory space. However, being coherent,
there was never a need for bus_dma to use uncached addresses.
This means that, on the only systems where uncached_base was not set to
PHYS_TO_XKPHYS(0, CCA_NC), it was never used.
Remove the variable, and replace PHYS_TO_UNCACHED() with
PHYS_TO_XKPHYS(, CCA_NC). No functional change.
