riscv: make t-head erratas depend on MMU 



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: a35707c3 ("riscv: add memory-type errata for T-Head")
Fixes: d20ec752 ("riscv: implement cache-management errata for T-Head SoCs")
