tree: Remove forward-declarations of structs for spi masters
Reorder functions to avoid forward-declarations of structs. Similar thing was done earlier for functions declarations, this patch takes care of structs declarations. BUG=b:140394053 TEST=builds objdump -d is identical objdump -s only difference is version number Change-Id: I256bd7c763efc010fc1f29f7c5853f150ac10739 Signed-off-by: Anastasia Klimchuk <aklm@chromium.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/51731 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: Edward O'Callaghan <quasisec@chromium.org>
