For some controllers PHYs can be optional. Handling NULL pointers without
crashing nor failing, makes it easy to handle optional PHYs.

Fix this sort of warning if generic-phy.h is included:
include/generic-phy.h:52:42: warning: ‘struct ofnode_phandle_args’ declared inside parameter list will not be visible outside of this definition or declaration
int (*of_xlate)(struct phy *phy, struct ofnode_phandle_args *args);

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.

To avoid compilation breakage on platform that doesn't
support DM PHY but uses xhci-dwc3 driver, add the missing
CONFIG_PHY flag.
Introduced by patch :

This allow to check if a PHY has been correctly
initialised and avoid to get access to phy struct.

The PHY framework provides a set of APIs to control a PHY. This API is
derived from the linux version of the generic PHY framework.
Currently the API supports init(), deinit(), power_on, power_off() and
reset(). The framework provides a way to get a reference to a phy from the
device-tree.
