ARM: rpi_b: disable rpi_b dcache explicitly
There appears to be no implementation of flush_dcache_range() for ARM1176, so explicitly disable dcache support to avoid references to that function from the LCD core in the next patch. This was presumably not noticed before simply because no drivers for the rpi_b were attempting DMA. Signed-off-by: Stephen Warren <swarren@wwwdotorg.org>
