The USB extal clock reference isn't associated to a crystal, it's
assoicated to a programmable clock, so remove the extal reference,
add the usb2_clksel.  Since usb_extal is referenced by the versaclock,
reference it here so the usb2_clksel can get the proper clock speed
of 50MHz.

i.e. will queue in renesas-devel for v5.14, with the above fixed.
