[PATCH v4 04/16] phy: tegra: xusb: tegra210: Do not reset UPHY PLL

[JC Kuo <jckuo@nvidia.com>]

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.
