[PATCH wireless-next v2 5/5] b43: N-PHY: add the missing override to the rev7 TX_PU command

[Luca Casati <luk00casati@gmail.com>]

brcmsmac's NPHY_REV7_RfctrlOverride_cmd_tx_pu also sets field 0x4 of
rev7 override bank 2 (REV7_RF_CTL_OVER5/6); b43 left it out. With it,
the override writes match brcmsmac and the wl driver on a BCM43228.

mmiotraces: https://github.com/Luca00casati/b43patch/blob/755c2d8/traces/excerpts/patch5-tx-pu.txt

Found and fixed with the help of an AI coding assistant (Claude Opus 5.5),
by comparing mmiotraces of b43 and wl on the same card.
