QEMU currently always triggers an illegal instruction exception when code
attempts to read the time CSR. This is valid behavor, but only if the TM bit in
mcounteren is hardwired to zero. This change also corrects mcounteren and scounteren CSRs to be 32-bits on both
32-bit and 64-bit targets.

Thanks for the patch.
Can you wrap your commit message at ~70 lines?

Isn't CSR_TIME & 31 just 0? Can this just be changed 1 << 1 or even
better add a macro?
Otherwise this patch looks good :)

Sure.

Any of those options work. Unless anyone feels strongly otherwise, I'll add
macros for the bits associated with the three named counters but not the
remaining 29 unnamed "high performance counters".
