I intentionally did not do this before, and I don't think it's right,
certainly right now. This fixes some boards (such as some mediatek SoCs
for example) that have boostd, have no bootcmd in environment and so
don't autoboot before bootstd, but do now. But it also bloats all of the
platforms that don't want bootstd because they have a real bootcmd
that's not some variant of "prepare to and then run distro_bootcmd".
Those should get bootstd disabled, first. Then we can evaluate if this
ends up being the right option.
