This series completes b43 support for the Broadcom N-PHY revision 8
paired with radio 2057 revision 8. b43 already supports the surrounding
PHY family - N-PHY rev 8 with radio 2057 rev 5 and rev 7 are handled,
and rev 16 with radio 2057 rev 9 is handled - but the rev 8 + rev 8
combination falls through four dispatcher gaps:

  - radio_2057.c, r2057_upload_inittabs(), case 8 lists radio_rev 5
    and 7 only;
  - radio_2057.c, r2057_get_chantabent_rev7(), case 8 lists radio_rev
    5 only;
  - tables_nphy.c, b43_nphy_get_ipa_gain_table(), case 8 lists
    radio_rev 5 only;
  - radio_2057.c carries r2057_rev8_init[] as a 54-entry stub commented
    out with "TODO: Which devices should use it?".

Two further pieces of plumbing are needed to reach those dispatchers
in the first place: d11 core revision 0x16 is missing from the b43
bcma id table, firmware name, and the corerev 22 / radio 2057 combination
needs the 24-bit indirect radio access path that brcmsmac uses for
the same silicon generation (see brcmsmac/phy/phy_cmn.c
read_radio_reg() / write_radio_reg()).

The series:

  1/7  b43: add firmware and initvals names for rev22
  2/7  b43: add d11 core revision 0x16 to id table
  3/7  b43: route d11 corerev 22 to 24-bit indirect radio access
  4/7  b43: support radio 2057 rev 8
  5/7  b43: add IPA TX gain table for N-PHY r8 + radio 2057 r8
  6/7  b43: add channel info table for N-PHY r8 + radio 2057 r8
  7/7  b43: add RF power offset for N-PHY r8 + radio 2057 r8

Patches almost reveal the bringup, the first two are swapped, as
applying 2/7 without 1/7 generate an immediate kernel panic caused
by a null deref.
From the third, each one fixes the next visible failure
in bring-up: 3/7 lets phy versioning read coherent radio identifiers,
4/7 unblocks the boot-time radio calibration that otherwise stalls,
and 5/7-7/7 fill the remaining 2.4 GHz dispatcher entries so
b43_nphy_set_channel completes to the default channel and core_init
proceeds past PHY init.

Tested on a D-Link DSL-3580L (Broadcom BCM6362 SoC, single-die 2.4 GHz
N-PHY rev 8 + radio 2057 rev 8 in 2.4 GHz IPA mode).

b43 is currently Orphan in MAINTAINERS. These patches do not add a
new chip family or PHY infrastructure; they fill four explicit
dispatcher gaps for a combination of an already-supported PHY and
an already-supported radio.

CHANGELOG:
v3: no changes, fighting with b4
v2:
  - Recovered the first patch of the series, so numbering is now /7
  - Added Assisted-By header
v1: https://lore.kernel.org/linux-wireless/8c0a07d2-9ec9-43d6-bdf7-f625bbb4a38a@mythread.it/
