net: dsa: Include platform_data header file

b53 and mv88e6xxx support passing platform_data, and now that we have
split the platform_data portion from the main net/dsa.h header file,
include only the relevant parts.

net: dsa: b53: Extend platform data to include DSA ports

The b53 driver already defines and internally uses platform data to let the
glue drivers specify parameters such as the chip id. What we were missing was
a way to tell the core DSA layer about the ports and their type.

Place a dsa_chip_data structure at the beginning of b53_platform_data for
dsa_register_switch() to access it. This does not require modifications to
b53_common.c which will pass platform_data trough.

net: dsa: b53: Add support for Broadcom RoboSwitch

This patch adds support for Broadcom's BCM53xx switch family, also known
as RoboSwitch. Some of these switches are ubiquituous, found in home
routers, Wi-Fi routers, DSL and cable modem gateways and other
networking related products.

This drivers adds the library driver (b53_common.c) as well as a few bus
glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and
memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx).

Basic operations are supported to bring the Layer 1/2 up and running,
but not much more at this point, subsequent patches add the remaining
features.
