List of required options is taken from there: https://wiki.gentoo.org/wiki/Docker (See also https://paste.sr.ht/~minlexx/5d454d210f29d45e6913120d7d301b931cec7c45 )

test plan:

$ pmbootstrap kconfig check --containers linux-postmarketos-qcom-msm8974  # passes
$ pmbootstrap kconfig check --containers linux-postmarketos-allwinner     # fails
