mb/pcengines/apu2: use AGESA 1.0.0.4 with adjusted AGESA header
PC Engines apu2 platform uses AGESA 1.0.0.4, because upstream AGESA 1.0.0.A doesn't work on apu2 - the platform doesn't boot. To properly utilize AGESA 1.0.0.4 we need to adjust AGESA header to state, which is compatible with AGESA 1.0.0.4 version. Cut out the changes introduced in CB:11225 exclusively for apu2 board. TEST=boot PC Engines apu2 and launch Debian Linux Change-Id: I3d85ee14e35dae8079e8d552b6530a3867f65876 Signed-off-by: Piotr Kleinschmidt <piotr.kleins@gmail.com> Signed-off-by: Michał Żygowski <michal.zygowski@3mdeb.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/35906 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de>

+ Due to a bug in AGESA 1.0.0.A affecting boards without UMA, it is
+ impossible to use the newest blob. Using an older 1.0.0.4 blob
+ workarounds the problem, however some headers changes between blob
+ revisions. This option removes the changes in headers introduced
+ with AGESA 1.0.0.A to fit the 1.0.0.4 revision.
