rtwn: update rtwn_get_rates() to separate out the CCK/OFDM and HT rates

rtwn: update rtwn_get_rates() to separate out the CCK/OFDM and HT rates

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.

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.
