Sorry if I'm still missing something :)

But doesn't this now block autoidle for all modules
with OCPIF_SWSUP_IDLE even if they work just fine with
autoidle?

I think what you want to do is keep clocks enabled
while in use?

If so, how about using HWMOD_CLKDM_NOAUTO:

"HWMOD_CLKDM_NOAUTO: Allows the hwmod's clockdomain to
 be prevented from entering HW_AUTO while hwmod is
 active."

Have you already tried what happens if you just tag
omap_hdq with HWMOD_CLKDM_NOAUTO?
