New China SRRC compliance readiness check
Proposed Change:
- China SRRC updates the testing requirement for 2.4/5GHz, the major changes are the in-band RSE limit, and EIRP limits.
- The SRRC updates impact both WLAN modules and platforms. The WLAN modules need to complete the new SRRC testing then platform can start to apply / renew the new SRRC cert. If platform took several WLAN modules but not all of the modules have completed the new SRRC testing updates, platform cannot renew/apply the new SRRC cert.
- The platforms which apply/renew SRRC new standards need to ensure the TX power can meet the new RSE/EIRP limits.
IHV confirmed below driver version can support these requirements.
Realtek:
The upstream driver can support SRRC compliance.

[SRU Justification]
BugLink: https://bugs.launchpad.net/bugs/2043964
[Impact]
SRRC (State Radio Regulation of China) compliance readiness check for Realtek WLAN.
[Fix]
Capability for Realtek WiFi TX power tables load and report from RFE (RF front end) parameters is needed. Multiple commits from vanilla kernel.
[Test Case]
```
$ sudo iw reg set CN
# manually connect to 5G ap : center channel 155 bw 80 M
$ sudo cat /sys/kernel/debug/ieee80211/phy0/rtw89/txpwr_table | grep -E 'MCS_2TX_80M_0|Regulatory'
```
The expected output s
```
Regulatory: CN
MCS_2TX_80M_0 - NON_BF BF | 10, 9, dbm
```
And verification fail output:
```
Regulatory: CN
MCS_2TX_80M_0 - NON_BF BF | 15, 10, dbm
```
[Where problems could occur]
This updates the behaviors and constraints of radio device power transmission for rtw89 driver, and must be done for regulatory compliance.
[Other Info]
As needed for oem-6.5/jammy, nominate only for Noble and oem-6.5/jammy.
