This patch fully removes the dependency of tuner-core on

Move tuner type ID check from tuner-core::set_type to simple_tuner_attach.
Since tuner-core forwards all attach requests to tuner-simple as the
default case, unless a specific attach function is specified in
set_type, this change is an appropriate cleanup.

tuner-types is needed for tuner-simple, and does not need to be bound
to tuner-core. Any caller of tuner-simple, including tuner-core, needs
to pass a structure from tuner-types into tuner-simple at attach-time.
Export the two needed symbols from tuner-types for now, so that card-level
drivers can attach tuner-simple for hybrid dvb_frontend devices. We will
remove this dependency altogether as tuner refactoring phase 3 progresses.

In commit e6bafba5b4, a bug was fixed that
involved converting !x & y to !(x & y). The code below shows the same
pattern, and thus should perhaps be fixed in the same way.
This is not tested and clearly changes the semantics, so it is only
something to consider.
The semantic patch that makes this change is as follows:
