701db6e9c6 net: ravb: Support reset GPIO both in mac and phy node
The recent DTs have the PHY reset GPIO in the PHY node rather than
the ethernet MAC node, support extracting the PHY reset GPIO info
from both the PHY node and ethernet MAC node.

536fb5d47c net: ravb: Filter out supported PHY features
The RAVB only supports 100Full and 1000Full operation, it does not support
10Full or any Half-duplex modes. The PHY could still advertise those features
though, so filter out the PHY features accordingly.

c4a8d9ca04 net: ravb: Do not shut down clock in start callback
Do not stop the clock in the start callback in case of failure, keep
them running to also keep the PHY running. The failure could be ie.
PHY failing to negotiate link and if the clock get shut down, another
attempt at bringing the link up would fail. The clock right now are
started in probe function and stopped in remove function, which is
the correct behavior.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

d64c789414 net: ravb: Initialize PHY in probe() once
Reset and initialize the PHY once in the probe() function rather than
doing it over and over again is start() function. This requires us to
keep the clock enabled while the driver is in use. This significantly
reduces the time between transfers as the PHY doesn't have to restart
autonegotiation between transfers, which takes forever.

90997cda76 net: ravb: Fix reset GPIO handling
Fix handling of the reset GPIO. Drop the _nodev() suffix from the
gpio_request_by_name() call as there is now a proper DM capable
GPIO driver. Also check if the GPIO is valid before freeing it in
remove path, otherwise U-Boot will crash.
