[PATCH v2] tee: optee: Change printing during optee_probe

[Ilias Apalodimas]

Right now the error messages when optee has a version mismatch or shared
memory is not configured are done with a debug().
That's not very convenient since you have to enable debugging to figure
out what's going on, although this is an actual error.

So let's switch the debug() -> dev_err() and report those explicitly.
