[coreboot] Depreciating FSP1.1 on soc/intel/quark along with util/checklist

[Arthur Heymans]

Dear community

soc/intel/quark Has 2 FSP versions hooked up, both FSP1.1 and FSP2.0.
Maintaining the code for both versions does increase the developers
load.

So my question is can we remove the older FSP1.1 implementation?
Is someone using this board in a setup that cannot be obtained with
FSP2.0?

There is only one board that has both FSP versions hooked up which can
be selected in menuconfig, so we wouldn't be dropping a board.

FSP1.1 on the Intel Galileo (only board using soc/intel/quark) is also
the only board that uses util/checklist. This utility allows to check
if certain linker symbols are found. Supposedly it allows board porters
to gradually work towards with a checklist of things to do while
in reality its just an extra burden to maintain a list of symbols.

So can we remove util/checklist? [1] does that.

Kind regards

Arthur Heymans
