wlcore: Allow memory access when the FW crashes

When the no_recovery flag is used, the recovery work will not restart
the FW and the state will not be set to 'on'. To enable post-mortem
analysis, allow memory access in the 'restarting' state.

Also, since the FW might not be operational, don't fail the read/write
operations if elp_wakeup fails.

mac80211: use legacy mode for all ACs

AVM FritzBox 7390 has a weird behaviour where once we enable
U-APSD only on the VO AC it limits the rate of the packets
it sends to 39Mbps and doesn't do AMPDU aggregation.
This causes a big degradation in throughput obviously.
It's important to note that this isn't related to PS and happens
also when ACTIVE is forced. The traffic affected is sent in BE AC.
Once legacy mode for all ACs is used the AP begins using higher rates
as well as AMPDU aggregation which improves throughput significantly.

In order to deal with this AP and potentially others switch to
using legacy mode for all ACs by default.

There are problems with BT voice if we don't use UAPSD mode for VO.
wlcore: check wl->state before setting default key

wl1271_op_set_default_key_idx() lacks a check
of wl->state, causing the driver to try writing
to a powered-off device in some cases (e.g.
during recovery)

wlcore: fwlog dynamic mem_block control

number of fwlog mem_blocks can be configured using module param.
this is a fw debug feature: in case a large fw log data is busrted during
a short period of time, the memory get filled and data is lost.
this allows us to dynamicly set the fw log mem_block usage, although
configuring more mem_block for logger comes at the expense of TP.

wl18xx: FDSP Clock (FDSP Code RAM Corruption fix)

In PG2.0 there is an issue where PHY's FDSP Code RAM sometimes gets
corrupted when exiting from ELP mode. This issue is related to FDSP
Code RAM clock implementation.

PG2.1 introduces a HW fix for this issue that requires the driver to
change the FDSP Code Ram clock settings (mux it to ATGP clock instead
of its own clock).

This workaround uses PHY_FPGA_SPARE_1 register and is relevant to WL8
PG2.1 devices.

The fix is also backward compatible with older PG2.0 devices where the
register PHY_FPGA_SPARE_1 is not used and not connected.

The fix is done in the wl18xx_pre_upload function (must be performed
before uploading the FW code) and includes the following steps:

1. Disable FDSP clock
2. Set ATPG clock toward FDSP Code RAM rather than its own clock.
3. Re-enable FDSP clock

wlcore/wl18xx/wl12xx: FW log params per chip arch

FW memory block size and FW log end marker parameters
are added to wl structure and are initialized per
chip architecture. convert_hwaddr hw operation is added
to convert chip dependent FW internal address.
Copy from FW log is also simplified to copy the entire
memory block as FW logger utility is repsponsible
for parsing of FW log content.

wlcore: add new plt power-mode: CHIP_AWAKE

Under this mode the chip is powered on including sdio
but no FW is downloaded and run, interrupts are not enabled, etc...

This mode is intended to allow RTTT to bridge sdio as a transport
to the chip.

Driver only provides sdio access using the dev_mem debugfs file.

Some fixes done to the code that ensures that PLT mode and normal
driver power mode (ifconfig/add_interface) are mutually excluded.

wlcore: disable elp sleep while in plt mode

We now disable elp sleep during plt mode to allow normal operation of

Having elp_sleep enabled during plt mode is actually not required and
in fact it disrupt plt operations such as rx statistics etc...

This is based on wl12xx (R5) commit 5cf0fe31ab

On ap start, the beacon is configured while
the basic rates were not set yet (they are

Since sometimes it's important to know
