[PATCH v3] wireless-regdb: add regulatory rules for Iraq (IQ)

[Mohammed Abdullah Ali Al-Obaidi]

Add a regulatory entry for Iraq (ISO 3166-1 alpha-2: IQ).

Iraq is currently absent from the database, so devices set to
country=IQ fall back to the world domain (00). The Iraqi
Communications and Media Commission (CMC) has published a numerical
national regulation covering Wi-Fi.

Source: Regulation on short-range radio communication devices (SRD)
and devices using ultra-broadband (UWB) technology, CMC Council of
Commissioners decision No. 122/q-2025, in force from 2025-09-22,
Article 4-1-13 (Wireless Access Systems):
https://cmc.iq/wp-content/uploads/2025/09/Regulation-on-short-range-radio-communication-devices-SRD-and-devices-using-ultra-broadband-UWB-technology.pdf

Limits as stated in the regulation:
  2400-2483.5 MHz: 100 mW, indoor/outdoor
  5150-5250 MHz:   200 mW, indoor
  5250-5350 MHz:   200 mW, indoor, DFS
  5470-5725 MHz:   1000 mW, indoor, DFS + TPC
  5725-5875 MHz:   2000 mW (10 MHz ch) / 4000 mW (20 MHz ch)
  5945-6425 MHz:   200 mW, indoor
  57-66 GHz:       10000 mW, indoor

Encoding notes:
 * 5470-5725 MHz: the regulation requires TPC, which Linux does not
   implement. Following EN 301 893, the limit is reduced from 30 dBm
   to 27 dBm. The upper edge is extended to 5730 MHz so that channel
   144 is usable, as the 5725-5875 MHz band is less restrictive.
 * 5725-5875 MHz: the 2000 mW limit for 10 MHz channels is used to be
   conservative, since the database holds one ceiling per band.
 * 5945-6425 MHz: encoded at 80 MHz pending clarification from the
   CMC regarding AFC requirements.

Notes:
    Changes since v2 (https://lore.kernel.org/wireless-regdb/20260521101501.1841-1-mnew_iraq@yahoo.com/):
    - Reduce 5470 MHz rule to 27 dBm (EN 301 893, no TPC); mention in commit message.
    - Extend 5470 MHz rule upper edge to 5730 MHz for channel 144, with comment.
    - Add comment for the conservative 2000 mW (10 MHz) limit at 5.8 GHz.
    - Use 10000 mW for 57-66 GHz, as in the regulation.
