This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.
Similar functionality was introduced for the rtnetlink core in
commit 5517750f05 ("net: rtnetlink - make create_link take name_assign_type")

This patch adds recovery mechanism for SDIO RX during SKB allocation
failures.
For allocation failures during multiport aggregation, we skip and drop RX
packets.
For single port read case, we will use preallocated card->mpa_rx.buf to
complete cmd53 read.
Now we terminate SDIO operations only upon cmd53 failures.

Now that we have wlcore device-tree bindings in place

wl12xx_platform_data struct, and move its members
into the platform device data (that is passed to wlcore)
Davinci 850 is the only platform that still set
the platform data in the legacy way (and doesn't
have DT bindings), so remove the relevant
code/Kconfig option from the board file (as suggested
