net: mvneta: Add network support for Armada 3700 SoC
Armada 3700 is a new ARMv8 SoC from Marvell using same network controller
as older Armada 370/38x/XP. There are however some differences that
needed taking into account when adding support for it:
* open default MBUS window to 4GB of DRAM - Armada 3700 SoC's Mbus
configuration for network controller has to be done on two levels:
global and per-port. The first one is inherited from the
bootloader. The latter can be opened in a default way, leaving
arbitration to the bus controller. Hence filled mbus_dram_target_info
structure is not needed
* make per-CPU operation optional - Recent patches adding RSS and XPS
support for Armada 38x/XP enabled per-CPU operation of the controller
by default. Contrary to older SoC's Armada 3700 SoC's network
controller is not capable of per-CPU processing due to interrupt lines'
connectivity. This patch restores non-per-CPU operation, which is now
optional and depends on neta_armada3700 flag value in mvneta_port
structure. In order not to complicate the code, separate interrupt
subroutine is implemented.
For now, on the Armada 3700, RSS is disabled as the current
implementation depend on the per cpu interrupts.

some ifdef and port to net-next for v4.10]
