825d646196 Include <cstdint> in common/kernel/hashlib.h 
The definitions for uint32_t, uint64_t report as undefined when
compiling under GCC13. They were previously found by transitive
includes, but this is not guaranteed to work, and GCC13 forced
the issue.

582410629b ice40: Don't assert on unknown extra_config bits if they are 0 
Bits are 0 by default anyway, so if they are unknown (because icestorm
is too od) but we want them at 0 ... it's not much of an issue.

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

6a1212a1e1 gowin: Add PLL support for the GW1NR-9 chip 
And also unified the fixing of PLL to bels: the point is that PLL being
at a certain location has the possibility to use a direct implicit wire
to the clock source, but once we decide to use this direct wire, the PLL
can no longer be moved.

f50d4c1ed1 ice40: Support for undriven / unconnected output ports 
If a port specified as output (and thus had a $nextpnr_obuf inserted)
is undriven (const `z` or const `x`), we make sure to not enable
the output driver. Also enable pull-ups if it was requested by the user.

0cf5006e3b ice40: Rework pull-up attribute copy to SB_IO blocks 
We try to copy the attribute only when there is a chance for
the output driver to not be active.

Note that this can _also_ happen when a port is specified as
output but has a TBUF, which the previous code wasn't handling.

We could copy the attribute "all-the-time" but this would
mean if a user specified a `-pullup yes` in the PCF for a
permanently driven output pin, we'd be burning power for
nothing.
