Bastian Koppelmann 656fdd1008 port_data: Refactor channel_route/connect_bitlines() 
both functions share a lot of code and are passing around a lot of data
under similar names (inst1, inst1_start_bit, inst1_bl_name, ...). Thus
we group all these elements in a named tuple to ease passing around
these elements.

All callers of channel_route/connect_bitlines() either pass in the bl/br
names or rely on "br_{}"/"bl_{}" as defaults. These hard coded values
should be determined by the instances. Thus we get the bitline names
based on the instances passed in. The callers only provide a template
string, to take care of the case that bitlines are called "bl_out_{}".

Bastian Koppelmann 5e1f64c8f9 modules/port_data: Add get_bl/br_name method 
if we rely on the names of the submodules (sense_amp_array,
write_driver_array, etc.) for port_data's pins, we get into trouble on
multiport SRAMs. To avoid this we use explicit names for br/bl depending
on the port number in port_data. Now each submodule does no longer need to
figure out the right name depending on the port number.
