bcm63xx: disable all devices with <= 4MiB flash and <= 32 MiB RAM

Device with 4 MiB flash and 32 MiB RAM won't be able to run OpenWrt in
a sufficient manner without tweaks, so don't build images for them by
default.

This includes all BCM6338, BCM6345 and BCM6348 "generic" devices,
as there are no supported devices of these with more than that.
