iwlwifi: remove forward debugfs function declarations

There's no need to have 'forward' debugfs function declarations
as part of the macros because the macros are always used after
the static functions are defined already, so remove them.

Use the new power table command (0xA9) to configure power management.
Use the legacy command (0x77) if FW does not support the new API.
New file power_legacy.c is introduced for legacy implementation.

iwlwifi: mvm: better handle several several vifs in BT Coex

When there one vif on 5GHz associating, it would clear all

iwlwifi: mvm: fix the ACK / CTS kill mask upon RSSI event

If a vif's RSSI gets good enough, we can enable reduced
Tx power. If so, we need to update the ACK / CTS kill mask
accordingly. Since the auditing for the interfaces was bad,
we enabled reduced Tx power, but didn't update the ACK / CTS
kill mask.
This is harmless since the firmware is most likely to
discard this setting anyway, but it is a good practice
to update it.

ARM: shmobile: Update romImage to relocate appended DTB

Instead of relying of MACH_TYPE for board identification,
update the romImage code to relocate an appended DTB to
the beginning of RAM. This implementation is independent
of ARM_APPENDED_DTB, this because it is necessary to copy
the DTB to memory so the kernel can access it.

Without this patch Mackerel does not boot via the Mask ROM
over USB (r_usb_boot) - this since non-DT boot was broken
ages ago in commit:
