rtwn: add tx power training for RTL8812/RTL8821

This apparently kicks off TX power level self-calibration, which
can't hurt.

Locally tested:

* RTL8812AU, STA
* RTL8821AU, STA

rtwn: fix rtl8812/rtl8821 vht definitions, add VHT calibration/rate control

* Add support for 80MHz channels during IQ calibration
* Correct the RAID flags for 1 and 2 stream VHT - the later ones
are for 2GHz VHT and then 3/4 stream VHT
* Add VHT to the RAID calculation for when we eventually transmit
VHT rates.

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.
