clk: qcom: Change gcc_usb3_phy_pipe_clk to gate_clk for MSM8992 



gcc_usb3_phy_pipe_clk's source could be dynamically gated off at any
time. Thus checking branch_clk status bit could result in stuck on/off
warnings. Since the HW design can handle clock input glitch, model
gcc_usb3_phy_pipe_clk as gate clock instead of branch_clk.

Also add gcc_usb3phy_phy_reset for asserting reset bit previously
associated to gcc_usb3_phy_pipe_clk branch.

This patch is simply a carbon copy of commit c32533e8 (clk: qcom:
Change gcc_usb3_phy_pipe_clk to gate_clk) which was for MSM8994.
