Different board types (ie. FPGA, HDK and DVP/EVB) require slightly
different init configuration options. Since we cannot probe the type
of board from the actual hardware, we need to pass it as an option
during module load.
This patch adds a module parameters that accepts the 3 different board
types, with DVP/EVB as the default, and uses this value where needed.

Set an alternate HT cap allowing MIMO rates (but only 20mhz) channels,
when the module is loaded with ht_mode=mimo.

Define the default HT capabilities of the 18xx chip family - these include
support for wide-channel.

Add a HW op to add extra enabled rates for AP-mode data-rates. Since
the rates might depend on channel properties, reconfigure AP-mode rates
when these change.
Implement the HW op for the 18xx family, where MIMO or wide-chan rates
can be added.

Parse the peer ht_cap element containing MCS8-MCS15 rates and pass it
to the FW. Rates unsupported by the HW will be sanitized by mac80211
before reaching us.

Translate the NL80211 channel type to a FW-specific channel type and send
it to the FW as part of the role-start command. For wl12xx this has no
effect - this element is treated as padding.

Track the current 802.11 channel type, defaulting to a NO_HT channel.
Update the channel type element when changed by mac80211.

Now wlcore requires the lower drivers to set the correct
configuration. Move the existing private configuration to the proper
place and add all generic configuration parameters.
The important changes are in Tx interrupt pacing and Rx BA window size.

Some chip families can checksum certain classes of Rx packets in FW.
Implement the Rx-checksum feature as a HW-op. For the 18xx chip-family,
set Rx-checsum according to indication from FW.

Some chip families are capable of checksumming certain classes of Tx
packets in HW. Indicate this fact in the netdev features and perform the
HW checksum by protocol type for the 18xx family.
Fix the location of the skb network header when we move it so we can
rely on it when setting the checksum.

Implement immediate Tx completion for the 18xx family. Move 18xx
specific Tx code to new tx.c/h files and create helper header files
for definitions.
