9dd68aa0e2 ice40: Take placed SB_GBs into account when placing PLLs 
Because the PLLs drive global networks, we need to account for
already existing and placed SB_GBs when trying to place/pack them.

Theses can be user instanciated SB_GBs with BEL attribute, or
SB_GB_IOs that got converted during the IO packing.

This patch assumes that:
 - If a PLL is used the output A global network is always used, even
   if there is no connection to the global output pin
 - If a PLL with a singe output is used, then the B output global
   network is still free to be used by whatever.

6cb4e2e83b ice40/pack: During IO packing, remove any unused input connection 
This is mostly for the benefit of PLL placement because the D_IN_x
ports are used for other purposes when PLL is enabled so we need to
make sure nothing is connected there already. (even an unused net is
too much)
