ice40: Add debugs to isBelLocationValid for SB_IO
...
When there is a constraint conflict while placing IOs, the user gets an
error message such as
ERROR: Bel 'X0/Y27/io1' of type 'SB_IO' is not valid for cell 'my_pin' of type 'SB_IO'
While this identifies the problematic cell, it does not explain why
there is a problem. Add some verbose messages to allow users to
determine where the problem is. This can result in something like
Info: Net '$PACKER_VCC_NET' for cell 'my_pin' conflicts with net 'ce' for 'ce_pin'
which provides something actionable.

Remove isValidBelForCell
...
This Arch API dates from when we were first working out how to
implement placement validity checking, and in practice is little used by
the core parts of placer1/HeAP and the Arch implementation involves a
lot of duplication with isBelLocationValid.
In the short term; placement validity checking is better served by the
combination of checkBelAvail and isValidBelForCellType before placement;
followed by isBelLocationValid after placement (potentially after
moving/swapping multiple cells).
Longer term, removing this API makes things a bit cleaner for a new
validity checking API.

ice40: Introduce the concept of forPadIn SB_GB
...
Those are cells that are created mainly to handle the various sources a
global network can be driven from other than a user net.
When the flag is set, this means the global network usually driven by
this BEL is in fact driven by something else and so that SB_GB BEL and
matching global network can't be used.
This is also what gets used to set the extra bits during bitstream
generation.
