This patch is based on MSIT Public Notification 2021-86 ("Unlicensed Radio
Equipment Established Without Notice"), officially announced on 2021-11-29.
The PSD must not exceed 2.5 mW/MHz if the frequency range includes all or
part of 5230-5250 MHz and the bandwidth is equal to or less than 40 MHz.
This leads to the following:
* 5230-5250 @ 20 -> 17 dBm
* 5210-5250 @ 40 -> 20 dBm
Here the power limit for >20 MHz bandwidth is also lowered to 17 dBm, as
it's not possible to set different power limits for different bandwidths
at the moment.
Extend the last 5 GHz frequency range to 5850 MHz.
Wi-Fi 6E is now allowed with the following restrictions:
* Indoor: the full 1.2 GHz range, up to 160 MHz bandwidth and 2 dBm/MHz PSD
* Outdoor: the lower 500 MHz range, up to 160 MHz bandwidth and 25 mW EIRP
Here only the former entry is added.
And also update the regulatory source links.

v4:
* merge 5210-5230 MHz band rule
* revert back to "indoor only" 6E rule as its power limit is higher
v3:
* update regulatory source to newer revision
* replace "indoor only" 6E rule with "both indoor and outdoor" rule
as "indoor only" rule limits PSD instead of EIRP
v2:
* split 5150-5250 MHz band rule to accommodate the PSD limit
* remove AUTO-BW flag from 6 GHz band rule

I'm curious about this power limit. In v1/v2 it was 24 dBm, then in v3
you lowered it for indoor/outdoor. Now you've chaned it back to indoor
only, but the limit is 15 dBm rather than the 24 you had in v1/v2. Why
the change?
24 dBm in v1/v2 was from max EIRP for 160 MHz, but I realized I should
use PSD instead of EIRP, and I got 2 dBm/MHz * 20 MHz = 15 dBm (to fit
the smallest bandwidth).
Regards,
Sungbo
