Merge pull request #574 from YosysHQ/gatecat/belpin-1

6bd3dba1e3 Remove the unused CellInfo::pins field 
No arches ever actually used this to implement a Cell->Bel pin mapping,
and in practice if any did try they would inevitably hit bitrot.

This field had limited use in practice as it is necessary to also
support cases where one cell pin maps to more than one bel pin. Removing
this old field is the first step towards developing a new API for this.

a8a27299ae Add pure-virtual ArchAPI interface 
This splits out the pure-virtual definition of the architecture API into
ArchAPI; leaving BaseArch to only provide default implementations (which
can now be completely opted out of by deriving from ArchAPI instead of
BaseArch).

8f76af40db nextpnr: Add base virtual functions for non-range Arch API 
This makes the Arch API clearer and also allows a base implementation of
functions to reduce the amount of complexity to get a basic Arch up and
running.

Currently this only implements these for functions that don't return a
range. Range-returning functions will require more work in order due to
the current 'duck typing' approach (probably a struct that contains the
range types combined with templating.)
