[PATCH v2] wireless-regdb: Update 6 GHz rules for South Africa (ZA)

ICASA Notice 1822 of 2023 (23 May 2023) amended Annexure B of the
Radio Frequency Spectrum Regulations, 2015, to allow licence-exempt
use of 5925-6425 MHz for WAS/RLAN.

The notice references ETSI EN 303 687 and defines two device
categories:

  LPI (Low Power Indoor): 23 dBm EIRP, indoor only
  VLP (Very Low Power):   14 dBm EIRP, no restriction

The current entry uses VLP power (14 dBm) with no indoor flag.
Update to LPI with the NO-OUTDOOR flag.

LPI is the appropriate choice because indoor WiFi is the primary
use case for 6 GHz. The VLP limit of 14 dBm is too low for
practical network operation with standard access points advertising
LPI power levels, causing repeated regulatory mismatch errors that
on MLO (Multi-Link Operation) setups disrupt the 6 GHz link.

Per maintainer guidance, only one rule per band is allowed, so this
replaces the VLP rule rather than adding the LPI rule alongside it.

Changes since v1:
  - Replace VLP rule with LPI rule per "one rule per band" guidance
    (Chen-Yu Tsai), rather than adding both.
  - Resend as standalone top-level patch. The previous v2 was sent
    inline as a reply on 2026-04-10, which the b4-ty tooling cannot
    extract. No content change from that v2.
