Currently VMEM/OCMEM/LLCC is disabled on all platforms.

Make it unconditional to save on space.

These caches will not be enabled until the Venus driver can reference
them as chunks of SRAM (they're modelled as separate devices) to avoid
hardcoding magic addresses and rougely accessing the hardware,
bypassing the normal accessors.

Agreed, this is dead code.
