Hm, that's really weird. Is the AMBA bus driver probed before the PIT
driver?
Anyway, I agree that this dummy clock approach is not ideal. Could we
make the apb_pclk clock optional in the AMBA bus driver?

The other approach would be to have someone claim the mck clock before
the AMBA bus driver, and keep it enabled.
