The PRUSS modules on AM43xx SoCs have a hardreset line and are controlled
by a PRCM reset line. Any clkctrl enable/disable operations cannot be
checked for module enabled/disabled status independent of the reset
operation, and this causes some unwanted timeouts in the kernel and
unbalanced states for the PRUSS clocks. These details should be handled
by the driver integration code itself.
Add the CLKF_NO_IDLEST flag to the PRUSS clkctrl clock so that these
module status checks are skipped.
