[PATCH v4 24/31] USB: fsl-mph-dr-of: remove now obsolete clock lookup name

[Gerhard Sittig]

after device tree based clock lookup became available, the peripheral
driver need no longer construct clock names which include the component
index -- remove the "usb%d_clk" template and unconditionally use "per",
remove the clock driver's clkdev registration
