Asserting reset to a PLL when it's managed by hardware power sequencer would
break sequencer's state machine. Putting PLL in reset doesn't save some extra
power.
Thanks for review.

Once UPHY PLL hardware power sequencer is enabled, do not assert
reset to PEX/SATA PLLs, otherwise UPHY PLL operation will be broken.
This commit removes reset_control_assert(pcie->rst) and
reset_control_assert(sata->rst) from PEX/SATA UPHY disable procedure.
