wireless-regdb: Update regulatory rules for Australia (AU) for June 2023

 - Update legislation link from March 2022 version to June 2023.
 - Add comments for each frequency range referring back to legislation.
 - Switch units from dBm to mW to match values listed in legislation.
 - Allow 5850-5875 at low power, as this has always been permitted.
 - Combine 5150-5350 bands to permit a 160 MHz channel.

[ saf:
  - eliminate overlapping rules
  - add AUTO-BW for 5730-5850 MHz and 5850-5875 MHz
  - change max bw for 5850-5875 MHz to 20 MHz ]

+# https://www.legislation.gov.au/Details/F2023C00524
 # Both DFS-ETSI and DFS-FCC are acceptable per AS/NZS 4268 Appendix B.
 # The EIRP for DFS bands can be increased by 3dB if TPC is implemented.
 # In order to allow 80MHz operation between 5650-5730MHz the upper boundary
 # of this more restrictive band has been shifted up by 5MHz from 5725MHz.
