[ Upstream commit 2a2018c3ac84c2dc7cfbad117ce9339ea0914622 ]
Both basic extensions of SVPBMT and ZICBOM depend on CONFIG_MMU.
Make the T-Head errata implementations of the similar functionality
also depend on it to prevent build errors.
Fixes: a35707c3d850 ("riscv: add memory-type errata for T-Head")
Fixes: d20ec7529236 ("riscv: implement cache-management errata for T-Head SoCs")
