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.
