Right now the code explicitly limits us to sha1,256 hashes with RSA2048
encryption. But the limitation is artificial since U-Boot supports
a wider range of algorithms.
The internal image_get_[checksum|crypto]_algo() functions expect an
argument in the format of <checksum>,<crypto>. So let's remove the size
checking and create the needed string on the fly in order to support
more hash/signing combinations.

This function will be called from x509_check_for_self_signed() and
pkcs7_verify_one(), which will be imported from linux in a later patch.
While it does exist in linux code and has a similar functionality of
rsa_verify(), it calls further linux-specific interfaces inside.
That could lead to more files being imported from linux.
So simply re-implement it here instead of re-using the code.

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.
