pcengines/apu2: implement POSTCAR_STAGE

This is done by removing BINARYPI_LEGACY_WRAPPER and adopting the code
to use hooks from state_machine.h.

No post codes are changed, except for those which were explicitly sent in
mainboard/romstage.c. Boot time is reduced by more than 7%, from 5.029s to
4.657s (coreboot timestamps, measured for loglevel 7).

POSTCAR_STAGE is required since coreboot 4.11 release.

TEST=boot PC Engines apu2 and launch Debian Linux with 4.14.50 kernel
