According to commit 40658534756f ("arm64: dts: rockchip: Add rock5b
overlays for PCIe endpoint mode"), Rock 5B can operate in PCIe endpoint
mode. For that to work, the rk3588-rock-5b-pcie-ep.dtbo overlay needs to
be applied on Rock 5B base Device Tree. If that Rock 5B is connected to
another Rock 5B, the latter needs to apply the
rk3588-rock-5b-pcie-srns.dtbo overlay.

In order to make sure the overlays are still valid in the future, let's
add a validation test by applying the overlays on top of the main base
at build time.

Looking good to me, thanks for the patch!  The employed approach was
already discussed and commented in detail in the v4 of this series, [*]
