riscv: cpu: check U-Mode before counteren write
The Priv ISA states:
"In systems without U-mode, the mcounteren register should
not exist."
Check U-Mode is present in MISA before writing to counteren, otherwise
we endup with Illegal Instruction exception on systems without U-Mode.
Also make checking MISA default for M-Mode.
