clk: qcom: gcc-x1e80100: Don't use parking clk_ops for QUPs
Per Stephen Boyd's explanation in the link below, QUP RCG clocks do not need to be parked when switching frequency. A side-effect in parking to a lower frequency can be a momentary invalid clock driven on an in-use serial peripheral. This can cause "junk" to spewed out of a UART as a low-impact example. On the x1e80100-crd this serial port junk can be observed on linux-next. Apply a similar fix to the x1e80100 Global Clock controller to remediate.
