Enables caching for the specified block of memory. This is accomplished
by setting the CE bit in the appropriate memory attribute register (MAR).
By default, caching is disabled for all memory spaces.
Note: This function does nothing on devices without L2 cache.
To enable caching for the range of memory from 0x80000000 to
0x80FFFFFF use:
CACHE_EnableCaching(CACHE_CE00);
