I tried clearing a bit by writing to hw_clkctrl_gpmi_clr, then busy-waiting for it to actually clear. My board hung. The data sheet agrees, these registers do not have _set, _clr, _tog, so fix up the definitions. git grep -E 'clkctrl_(gpmi|ssp[0-9])_' says that nobody uses those non-existing ops registers.
