v2: reworked patch
 - added user sw step
 - fixed help text
 - fixed hash and license info
v3: fixed build args
v4: fix missing util-linux dependency

--> Actually, I found this missing dependency after removing `$(eval $(kernel-module))`
and the kernel dependency, only then I was able to run `./utils/test-pkg -p sema-linux-ec -a`.
So there is not really a way to check for the generic package compilation by using
`./utils/test-pkg` when there is a kernel-module defined. We should perhaps fix that.

$ ./utils/test-pkg -p sema-linux-ec -a

  To: thomas; +Cc: buildroot, jorik.devreese, thomas.petazzoni

From: Devreese Jorik <jorik.devreese@barco.com>

Add the unified sema-linux package, which replaces the archived
sema-linux-ec repository from Adlink. This unified upstream repository
provides support for both BMC (Board Management Controller) and EC
(Embedded Controller) devices.
