Sylvain Munaut 49ae495344 ice40: Add support for PLL ICEGATE function 
Technically you can enable it independently on CORE and GLOBAL
output, but this is not exposed in the classic primitive, so
we do the same as icecube2 and enable/disable it for both output
path depending on the argument

Sylvain Munaut 325d46e284 ice40/chipdb: Add wires to global network for all cells that can drive it 
The icebox DB is a bit inconsistent in how global network connections
are represented. Here we make it appear consistent by creating ports
on the cells that can drive it.
