clk: qcom: Move gcc_usb3_phy_pipe_clk to branch clock

Browse source 
A clk_disable on gate clocks would hold a global
spinlock and it would wait for a halt_delay. In some
race conditions(due to longer delays for gate clocks)
if any other CPU would also invoke a clk_disable then
it could result in a spinlock lockup. Avoid this by
moving the gcc_usb3_phy_pipe_clk clk to branch clock.
