10G switch requires forward port number in the taginfo field,
where as it should be in packet_info field for necp 1.4 Ethss. So
fill this value correctly in the knav dma descriptor.
Also rename dma_psflags field in struct netcp_tx_pipe to switch_to_port
as it contain no flag, but the switch port number for forwarding the
packet. Add a flag to hold the new flag, SWITCH_TO_PORT_IN_TAGINFO which
will be set for 10G. This can also used in the future for other flags for
the tx_pipe.

Ethss has multiple modules within the sub system
- switch sub system
- sgmii
- mdio
- switch module
NetCP driver re-uses existing davinci mdio driver. It requires to
have its own register region to map the reg space. So restructure
the code to use separate reg region for the individual modules it
manages. Use range property to define register space of NetCP and
use reg property to define individual reg spaces. So MDIO will have
its own reg space to map. This is a pre-requisite to enable MDIO
driver for NetCP.

From: WingMan Kwok <w-kwok2@ti.com>
NetCP 1.5 available on newer K2 SoCs such as K2E and K2L introduced 3
variants of the ethss subsystem, 9 port, 5 port and 2 port. These have
one host port towards the CPU and N external slave ports.
To customize the driver for these new ethss sub systems, multiple
compatibility strings are introduced. Currently some of parameters that
are different on different variants such as number of ALE ports, stats
modules and number of ports are defined through constants. These are now
changed to variables in gbe_priv data that get set based on the
compatibility string. This is required as there are no hardware
identification registers available to distinguish among the variants
of NetCP 1.5 ethss. However there is identification register available
to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use
of in the code to differentiate them.
For more reading on the details of this peripheral, please refer to the
User Guide available at http://www.ti.com/lit/pdf/spruhz3
