riscv: sifive: Apply errata "cip-1200" patch 
For certain SiFive CPUs, "sfence.vma addr" cannot exactly flush addr
from TLB in the particular cases. The details could be found here:
https://sifive.cdn.prismic.io/sifive/167a1a56-03f4-4615-a79e-b2a86153148f_FU740_errata_20210205.pdf
In order to ensure the functionality, this patch uses the Alternative
scheme to replace all "sfence.vma addr" with "sfence.vma" at runtime.
