The b53_io_ops structures are never modified, so declare them as const.
Done with the help of Coccinelle.

net: dsa: b53: Add BCM7445 quirk2016-06-10T05:21:29ZFlorian Fainellif.fainelli@gmail.com2016-06-10T01:23:54Zurn:sha1:0830c9802e33d8c94b9b2f89b3db4aae92e55bf6
The Broadcom BCM7445 STB chip has an issued in its revision D0 which was
previously worked around in drivers/net/dsa/bcm_sf2.c where we may
end-up double programming the integrated BCM7445 switch (bcm_sf2) and an
external Broadcom switch such as BCM53125, since these are mostly
register compatible.
Add a small quirk which just defers probing until we are sitting on the
slave DSA MDIO bus, which will allow us to intercept reads/writes and
funnel them through the SF2 internal MDIO master (which happens to
disconnect its pseudo PHY).

net: dsa: b53: Add support for Broadcom RoboSwitch2016-06-10T05:21:29ZFlorian Fainellif.fainelli@gmail.com2016-06-10T01:23:53Zurn:sha1:967dd82ffc52e9d8ea0defde094f9a39a3f4eeed
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.
