Fix waitus() waitus() was missing an instruction barrier before reading the system counter value. As a result, the CPU could speculatively read it and we would potentially base our delay loop on stale values. waitus() now uses the syscounter_read() helper function introduced in the previous patch, which has the required ISB.
