Subject: [PATCH v2 4/5] riscv: fix dependency for t-head errata

alternatives only work correctly on non-xip-kernels and while the
selected alternative-symbol has the correct dependency the symbol
selecting it also needs that dependency.

So add the missing dependency to the T-Head errata Kconfig symbol.
