4.16-stable review patch. If anyone has any objections, please let me know.

From: Tero Kristo t-kristo@ti.com
commit 269bd202bc0fd04e841cb123867fd3f49e04ace9 upstream.
The introduction of support for CLK_SET_RATE_PARENT flag for clkctrl clocks used a generic clock flag, which causes a conflict with the rest of the clkctrl flags, namely the NO_IDLEST flag. This can cause boot failures on certain platforms where this flag is introduced, by omitting the wait for the clockctrl module to be fully enabled before proceeding with rest of the code.
Fix this by moving all the clkctrl specific flags to their own bit-range.
