Allow the driver to wake/stop the queues for multiple reasons. A queue
is started when no stop-reasons exist.
Convert all wake/stop queue calls to use the new API.
Before, a stopped queue was almost synonymous a high-watermark on Tx.
Remove a bit of code in wl12xx_tx_reset() that relied on it.
Internal packets arriving from mac80211 are also discarded when a queue
is stopped. A notable exception to this is the watermark reason, which
is a "soft"-stop reason. We allow traffic to gradually come to a halt,
but we don't mind spurious packets here and there. This is merely a flow
regulation mechanism.

those requests and starts service the next roc request as
soon as the driver sends a croc for the previous one. So,
if the fw rocs on channel X and driver asks to roc also
on channel Y, the fw will not start service Y (and will
not send roc complete event for this request) until the
driver releases the fw with croc X.

Commit 4afc37 (wlcore: reorder identify_chip and get_hw_info) broke

When we moved the identify_chip operation to an earlier stage (ie. to
the probe function), we broke wl127x support because during HW init we
would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN.
To avoid this, set this quirk in the identify_chip operations and only
force it to be unset if the bus module doesn't support it. We were
doing the opposite and setting the flag if the bus module supports it.
