- Add a missing shift in schizo_get_timecount(). This happened to be non-fatal
as STX_CTRL_PERF_CNT_CNT0_SHIFT actually is zero, if we were using the
second counter in the upper 32 bits this would be required though as the MI
timecounter code doesn't support 64-bit counters/counter registers.
- Remove a redundant NULL assignment from the timecounter initialization.
