I think this should best be submitted / discussed separately from the
q35 patch series.  And dropping the dsdt from seabios will should
actually be the last step.  Loading via fw_cfg works even when seabios
has a builtin dsdt.  So we can start loading the dsdt via fwcfg
unconditionally in qemu without touching seabios.  Once everything is in
place in qemu we can finally zap the builtin dsdt in seabios (or make it
a config option so latest seabios continues to work with older qemu
