Radhey Shyam Pandey 10bda7ac2a arm64: zynqmp: Revert usb node drive strength and slew rate for zcu106 
[ Upstream commit 767ecf9da7 ]

On a few zcu106 boards USB devices (Dell MS116 USB Optical Mouse, Dell USB
Entry Keyboard) are not enumerated on linux boot due to commit
'b8745e7eb488 ("arm64: zynqmp: Fix usb node drive strength and slew
rate")'.

To fix it as a workaround revert to working version and then investigate
at board level why drive strength from 12mA to 4mA and slew from fast to
slow is not working.
