Pipe clock comes out of the phy and is available as long as
the phy is turned on. Clock controller fails to gate this
clock after the phy is turned off and generates a warning.

Presently, the phy pipe clock's name is assumed to be either
usb3_phy_pipe_clk_src or pcie_XX_pipe_clk_src (where XX is the
phy lane's number). However, this will not work if an SoC has
more than one instance of the phy. Hence, instead of assuming
the name of the clock, fetch it from the DT.

Adding vendor specific directories in phy to group
phy drivers under their respective vendor umbrella.
Also updated the MAINTAINERS file to reflect the correct
directory structure for phy drivers.
