riscv: Add sfence.vma after early page table changes
[ Upstream commit 21190b74bcf3a36ebab9a715088c29f59877e1f3 ]
This invalidates local TLB after modifying the page tables during early init as
it's too early to handle suprious faults as we otherwise do.
Fixes: f2c17aabc917 ("RISC-V: Implement compile-time fixed mappings")
