While looking into an MTU issue with sfc, I started noticing that almost
every NIC driver with an ndo_change_mtu function implemented almost
exactly the same range checks, and in many cases, that was the only
practical thing their ndo_change_mtu function was doing. Quite a few
drivers have either 68, 64, 60 or 46 as their minimum MTU value checked,
and then various sizes from 1500 to 65535 for their maximum MTU value. We
can remove a whole lot of redundant code here if we simple store min_mtu
and max_mtu in net_device, and check against those in net/core/dev.c's
dev_set_mtu().
In theory, there should be zero functional change with this patch, it just
puts the infrastructure in place. Subsequent patches will attempt to start
using said infrastructure, with theoretically zero change in
functionality.

We keep running into cases where device drivers want to know the exact
version of the a SoC they are currently running on. In the past, this has
usually been done through a vendor specific API that can be called by a
driver, or by directly accessing some kind of version register that is
not part of the device itself but that belongs to a global register area
of the chip.
Common reasons for doing this include:
- A machine is not using devicetree or similar for passing data about
on-chip devices, but just announces their presence using boot-time
platform devices, and the machine code itself does not care about the
revision.
- There is existing firmware or boot loaders with existing DT binaries
with generic compatible strings that do not identify the particular
revision of each device, but the driver knows which SoC revisions
include which part.
- A prerelease version of a chip has some quirks and we are using the same
version of the bootloader and the DT blob on both the prerelease and the
final version. An update of the DT binding seems inappropriate because
that would involve maintaining multiple copies of the dts and/or
bootloader.
This patch introduces the soc_device_match() interface that is meant to
work like of_match_node() but instead of identifying the version of a
device, it identifies the SoC itself using a vendor-agnostic interface.
Unlike of_match_node(), we do not do an exact string compare but instead
use glob_match() to allow wildcards in strings.

USB erratum-A006918 workaround tries to start internal PHY inside
uboot (when PLL fails to lock). However, if the workaround also
fails, then USB initialization is also stopped inside Linux.
Erratum-A006918 workaround failure creates "fsl,erratum_a006918"
node in device-tree. Presence of this node in device-tree is
used to stop USB controller initialization in Linux
