wlcore: fix broken TX due to wrong queuing of recovery
commit
14bba17b "wl12xx: Propagate errors from wl1271_raw_write32"
breaks down TX in certain scenarios. wl1271_irq_locked() propagates
errors from wl1271_tx_work_locked however it may return -EBUSY
when the FW queues are full which is a legitimate case and not a
a real error. In this case a recovery is triggered by wl1271_irq
and this keeps repeating itself so TX is completely broken.
Fix it by avoiding propagating return values as errors even if they
aren't. Only bus (SDIO or SPI) ops failures would be progagated
as only these should trigger recovery.

wlcore: Fix sdio out-of-sync power state
wl12xx_sdio_power_off() manually powers down the card regardless of the
runtime pm state. If wl12xx_sdio_power_on() is called before the card
was suspended by runtime PM, it will not power up the card.
As part of the HW detection, the chip's power is toggled. Since this
happens in the context of probing sdio, the power reference counter will
be higher than zero. As a result, when wl12xx_sdio_power_off() is
called, the chip will be powered down while still having a positive
power reference counter. If the interface is quickly activated, the
driver might try to transfer data to a powered off chip.
Fix this by ensuring that wl12xx_sdio_power_on() explicitly powers on
the chip in case runtime pm claims the chip is already powered on. To
avoid cases in which it is not possible to determine if the chip was
really powered on (card's power reference counter is positive), operate
on the mmc_card instead of the function.
Also verify that the chip is indeed powered on before powering off, to
avoid wrong reference counter values in error cases.

FW memory blocks allocated for the log buffer are handled as a link list:
the first 4 bytes in each memory block contain FW address to the next block.
The end of list condition depends on FW log mode:
- on demand: the list is cyclic, the next address is equal to the first address
- continuous: the address is equal to 0x2000000
Log data resides inside FW memory block with offset depending on

wl18xx: add power limit reference value to mac_and_phy settings
With more recent PHY firmware versions (>8.1.0.0.116), we need to use
the correct value for the pwr_limit_reference_11_abg parameter when
setting the mac_and_phy options.
For now we use a hardcoded 0xc8 as the value. This will be moved to
the configuration binary when it gets implemented.

wl18xx: add module parameter to force SISO 20MHz
In some cases it may be useful to force narrow-band SISO channels.
Add a new value to the ht_mode module parameter to force the device to
operate in SISO 20MHz.
