scripts: checkpatch: revert code modification

Checkpatch code should not be modified directly. When the code
is updated to a next version, any local modifications would
be lost and needed to be done again.

Camelcase check is enabled again. Exceptions to camelcase are
allowed e.g. when calling an external library interface.
