There is a number of users that use uclass_first_device to access the
first and (assumed) only device in uclass.
Some check the return value of uclass_first_device and also that a
device was returned which is exactly what uclass_first_device_err does.
Some are not checking that a device was returned and can potentially
crash if no device exists in the uclass. Finally there is one that
returns NULL on error either way.
Convert all of these to use uclass_first_device_err instead, the return
value will be removed from uclass_first_device in a later patch.

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.

We don't need this anymore - we can use device tree and the new pinconfig
driver instead.
