clock/lattice_ecp5/ECP5PLL: implement 4-output solver
...
Reimplement the configuration loop to allow all 4 outputs to be used by
the user, if one of them is suitable for use as VCO feedback.
The new strategy is to first iterate over requested outputs to see if
any of them can be used as a feedback source. If one can, it is
selected, and if no output is suitable, it attempts to instantiate one.
Once the feedback path is selected, the VCO frequency is known and it
attempts to calculate the remaining outputs' settings.
In addition, this implementation now respects datasheet limits in two
new ways:
- It respects the post-input-divider minimum frequency of 10MHz
- It respects the max output frequency of 400MHz for instantiated
feedback outputs
I am slightly unhappy with the seemingly-repetitive for loops. However
each one has slightly different sematics and I don't see a way to
combine them that doesn't hinder readability.

...
Some targets have multiple alt settings for DFU for different zone
of the flash. Allowing to specify which one to flash and not
rebooting immediately allows to flash several of them at once.

soc/cores/ram: allow populating initial values in Nexus LRAM
...
On designs which use Nexus parts without any external memory, it can be
difficult to fit an embedded ROM program larger than a few KiB. Radiant
cannot infer LRAM, and refuses to infer EBRAM under many circumstances
too, so large memories tend to just consume a huge number of LUTs.
This patch makes it possible to explicitly wire up an LRAM as a ROM,
populate its initial values with a program, and execute directly from
it. That lets us embed programs up to 64KiB.
