Add the 2.4 GHz IPA TX gain table for N-PHY rev 8 paired with radio 2057 rev 8 and wire it to the existing dispatcher. b43_nphy_get_ipa_gain_table() in tables_nphy.c currently handles case 8 only for radio_rev == 5; radio_rev == 8 falls through and the function logs: b43-phyX ERROR: No 2GHz IPA gain table available for this device b43-phyX ERROR: PHY init: Channel switch to default failed leaving b43_phy_init() to return an error and core_init to abort before the MAC is enabled. The new b43_ntab_tx_gain_ipa_2057_rev8_2g[] is 128 u32 entries, matching the layout of the existing b43_ntab_tx_gain_ipa_2057_ rev5_2g and b43_ntab_tx_gain_ipa_2057_rev9_2g siblings in this file. Each entry packs five gain fields decoded by wlc_phy_get_tx_gain_nphy in the proprietary driver, the same encoding b43 uses for the other 2057 IPA tables. The high byte of every entry differs from the rev 5 sibling (0x40 vs 0x30): different PAD-gain code prefix for the rev 8 front-end. The low 24 bits coincide with rev 5 across the whole table - the gain step amplitudes are the same, only the PAD-gain selector prefix changes. Values extracted from an MMIO dump of the proprietary Broadcom wl driver running on BCM6362 silicon (wl driver 6.30.102.7). Encoding cross-validated by re-deriving the in-tree rev 5 table from the same source using the same extraction method - the result matches b43_ntab_tx_gain_ipa_2057_rev5_2g byte-for-byte.
