Fails on RISCV when sv57 is enabled

[Alexandre Ghiti]

RISC-V introduced SV57 (57bit physical addresses) which breaks the pointer tagging mechanism of Go, we need the following patch to fix that: https://groups.google.com/g/golang-codereviews/c/qgCDki-2zEA?pli=1

Note that at the moment, the kernel disables sv57 to work around this issue.
