Greentime Hu d411cf02ed riscv: fix scratch register clearing in M-mode. ...

This patch fixes that the sscratch register clearing in M-mode. It cleared
sscratch register in M-mode, but it should clear mscratch register. That will
cause kernel trap if the CPU core doesn't support S-mode when trying to access
sscratch.

Fixes: 9e80635619 ("riscv: clear the instruction cache and all registers when booting")
