mwl8k: fix firmware command serialisation

The current mwl8k_priv->fw_lock spinlock doesn't actually protect
against multiple commands being submitted at once, as it is not kept
held over the entire firmware command submission.  And since waiting
for command completion sleeps, we can't use a spinlock anyway.

To fix mwl8k firmware command serialisation properly, we have the
following requirements:
- Some commands require that the packet transmit path is idle when
  the command is issued.  (For simplicity, we'll just quiesce the
  transmit path for every command.)
- There are certain sequences of commands that need to be issued to
  the hardware sequentially, with no other intervening commands.

This leads to an implementation of a "firmware lock" as a mutex that
can be taken recursively, and which is taken by both the low-level
command submission function (mwl8k_post_cmd) as well as any users of
that function that require issuing of an atomic sequence of commands,
and quiesces the transmit path whenever it's taken.

b43: LP-PHY: Update baseband init for recent spec changes

The spec had some nasty typos, and a large part of the rev0/1 BB
init procedure was also missing. Fix these.

Also make the init-time channel switch debuggable.

(The change from -EINVAL to -EIO is simply to make it possible
to distinguish the PLL charge pump error from a channel-not-found
error.)

The driver must explicitly set ps_default to false,
