nyan: nyan_big: Mark the address range covering the SRAM as cachable.
The SRAM is very likely faster than going all the way out to DRAM for data,
but I don't think it's part of the cores themselves and won't be as fast as
the L1 caches. Enabling caching for this region reduces the time it takes to
get to the payload by about 75% when serial output is disabled and the main
part of display init is commented out.

TEST=Built and booted on nyan.
