Move default y configs out of arch/board Kconfig

Some archs/boards specify their own default by pre-defining the config
which causes the Kconfig system to mix up the order of the configs in
the defconfigs... This will cause merge pain if allowed to proliferate.

Remove the configs that behave this way from the archs.

A few configs still remain, but that is because they only exist as
defaults and do not have a proper Kconfig entry. Those appear to be:
