Allow the driver to wake/stop the queues for multiple reasons. A queue

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

When we moved the identify_chip operation to an earlier stage (ie. to

would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN.
To avoid this, set this quirk in the identify_chip operations and only

doing the opposite and setting the flag if the bus module supports it.
