[D][E][SRU][PATCHv2 0/1] Enable Armada SOCs and MVPP2 NIC driver for disco/generic arm64

V2: drop CONFIG_ARCH_MULTI_V7 and add configs with updateconfigs as
suggested by ppisati.

== SRU Justification ==
The mvpp2 is a driver for network controllers(s) in Marvell SOCs,
particularly Armada 8040.

However this driver was neither enabled as a module or a built-in for
Disco arm64.

== Fix ==
Just like what we did for armhf, set CONFIG_MVPP2 to "m" for arm64 can
solve this problem.

We need to enable the Armada SOCs support (CONFIG_ARCH_MVEBU) as well
to meet the dependency requirement.

Other configs were added by the updateconfigs process.

== Test ==
A test kernel for Disco ARM64 could be found here:
https://people.canonical.com/~phlin/kernel/lp-1835054-mvpp2/V2/

User has confirmed that the V1 kernel can fix this missing driver
issue (V2 is just with CONFIG_ARCH_MULTI_V7 dropped and some configs
added explicitly, I have it tested on an ARM64 node, the mvpp2 module
can be loaded without any issue).

== Regression Potential ==
Low, this patch just enable the Armada SOCs and make this mvpp2 driver
to be built as a module on ARM64, and we already have those for armhf.
