820bad0271 arm64: zynqmp: Disable Tri-state for MIO38 Pin 
gpio38 is used in SOM's kv260 to reset the Ethernet PHY.
At present, HW reset is not working properly as Tri-state 
is enabled for MIO38, causing inappropriate PHY register reads.

Disabled Tri-state for MIO38 to make HW reset work.

Tri-state disable :
ZynqMP> md 0xFF180208 2

Tri-state enable :
ZynqMP> md 0xFF180208 2
ff180208: 00bfe7e3 00000540

8daa786211 arm64: zynqmp: Sync licenses with Linux kernel 
There is difference between licenses in the Linux kernel and there
shouldn't be any diff because all changes are coming from the same source
at the same time. The difference is really in a time when they were
upstreamed. That's why sync it up.
