msm: clock-8084: Change the halt check type for UFS and PCIE clocks

UFS symbol clocks and PCIE pipe clocks have external sources. Due to
HW design, there is no guarantee that 1) the downstream branch clocks
are turned on after turning on the sources; 2) the downstream branch
clocks are turned off before turning off the sources.

Therefore, make the halt check for these clocks as delay instead of
polling the status bit to avoid warnings.
