soc/amd/*/Makefile: use all_x86 target

Use the newly introduced 'all_x86' make target to add the compilation
unit to all stages that run on the x86 cores, but not to verstage on
PSP.

TEST=Timeless builds for Mandolin without verstage on PSP and Guybrush
with verstage on PSP result in identical images with and without this
patch applied.
