Octeon exposes CvmCount through RDHWR register 31. Add the Octeon-only
decode path, enable the corresponding HWREna bit for linux-user, and use
an unsigned mask when checking HWREna so bit 31 is handled safely.
For user-mode emulation, return host ticks as a monotonic counter source
suitable for existing Octeon userspace code. In system mode, fall back to
the existing CP0 Count value.
