rtwn: only set INIRATE if we're not doing firmware rate control.

This register (array) controls the initial rate to use for each
MACID. There's no need to set it if firmware rate control is enabled -
it'll actually be under firmware control (and we can read it back to
see what choices the firmware is making.)

rtwn: bring the r92c rate control setup selection in line with tx descriptors

The rate control message was doing 11g+11n without 11b rates, but
the TX descriptor setup supports also falling back on 11b rates
when doing multi-rate retry / per-descriptor rate control.

So, line them up. They're not exactly the same as the TX path
supports pure-N and pure-G modes which the rate control configuration
does not, but there'll need to be a lot more work on supporting
those operating modes anyway (around things like self-generated
frame rate control/masks, beacon config, RTS/CTS selection, etc.)

The 32 bit bitmap is enough for CCK/OFDM rates and MCS0..15, but
won't work for > MCS15, nor VHT rates.

So, break out the legacy rates and HT rates.

* break the rates and htrates out
* document which calls are looking up basic rates and which care
about the rates themselves
* ensure the rate bitmap passed into the rate control firmware call
(which isn't enabled yet!) is capped at 28 bits so they don't
set the mode field.

rtwn(4), urtwn(4): merge common code, add support for 11ac devices.

All devices:
- add support for rate adaptation via ieee80211_amrr(9);
- use short preamble for transmitted frames when needed;
- multi-bss support:
* for RTL8821AU: 2 VAPs at the same time;
* other: 1 any VAP + 1 sta VAP.
RTL8188CE:
- fix IQ calibration bug (reason of significant speed degradation);
- add h/w crypto acceleration support.
USB:
- A-MPDU Tx support;
- short GI support;
Other:
- add support for RTL8812AU / RTL8821AU chipsets
(a/b/g/n only; no ac yet);
- split merged code into subparts:
* bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*)
* common (if_rtwn*)
* chip-specific (rtl*/*)
- various other bugfixes.

Due to code reorganization, module names / requirements were changed too:
urtwn urtwnfw -> rtwn rtwn_usb rtwnfw
rtwn rtwnfw -> rtwn rtwn_pci rtwnfw

Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU.
