On the gta04 with a dm3730 omap_hdq does not work properly when the
device enters lower power states. Idling uart1 and 2 is enough
to show up that problem, if there are no other things enabled.
Further research reveals that hdq iclk must not be turned off during
transfers, also according to the TRM. That fact is also correctly described
in the flags but the code to handle that is incomplete.
To handle multiple users of a single ick, autoidle is disabled
when a user of that ick requires that (has the OCPIF_SWSUP_IDLE))
Changes v3:
- replace CLK_IS_BASIC
Changes v2:
- uses spinlocks instead of mutexes
- invert counter logic
- check whether clock type is basic
For this series it's best to merge it all via the
clock tree along with the related clock patches:

Sorry, I've just been pretty busy as usual, queued up for 5.1 now, thanks.
