Sylvain Munaut 9483a95a4a ice40: Improve the is_sb_pll40_XXX predicates collection 
- Add a test for dual output PLL variant
 - Make them handle the packet version of the cell

 This will become useful for various tests during PLL rework

Sylvain Munaut ac5d767d4f ice40/pack: Stop looking for BEL when we have one during PLL placement 
Ideally we should first process all the PLL that are constrained somehow
(either explicitely or because they are PAD) and then free place the rest.
