[PATCH 4/4] IPQ40xx: clk: add USB clock handling

[Robert Marko]

USB clocks were completely forgotten as driver would always return 0 even if clock ID was unknown.

This behaviour changed with "IPQ40xx: clk: dont always return 0" and this will now causes the USB-s to fail probing as clock enable will return -EINVAL.

So to fix that lets add all of the USB clocks to the driver.

Fixes: 430e1dcf ("IPQ40xx: Add USB nodes")
