The virtio-rng test to verify effective handling of oversized return
buffers checks that an (undocumented) error is raised, instead of the
real concern, which is the surrounding buffer integrity following a rng
function call.
Update the test to check that the other contents of a buffer remain
unchanged instead of looking for an error code.

The UT_TESTF_ macros read as 'unit test test flags' which is not right.
Rename to UTF ('unit test flags').

This has the benefit of being shorter, which helps keep UNIT_TEST()
declarations on a single line.

Give the enum a name and reference it from the UNIT_TEST() macros while
we are here.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from all "test/" files and when needed add
missing include files directly.

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.

Add a regression test for virtio-rng reading beyond the end of its
buffer if the virtio device provides an invalid length.
