[PATCH] arm64: defconfig: Enable PCI NTB support

[Aksh Garg]

Enable PCI Non-Transparent Bridge (NTB) functionality supported by
Texas Instruments J721E, J742S2 and J784S4 SoCs.

NTB_NETDEV provides a virtual ethernet interface over the NTB Transport
layer. This allows connected systems to communicate with each other
using standard network protocols, and transfer data as ethernet traffic.

Does not look at all like SoC-specific option, so I still do not see the
need in defconfig. This is not distro config. This is not even kernel
test config.

So why do we need generic options like that?
