4cc533830b wlcore: Prevent interaction with HW after recovery is queued
When a function requests to recover, it would normally abort and will
not send any additional commands to the HW. However, other threads may
not be aware of the failure and could try to communicate with the HW
after a recovery was queued, but before the recovery work began.

Fix this by introducing an intermediate state which is set when recovery
is queued, and modify all state checks accordingly.

b0f0ad39e3 wlcore: Propagate errors from wl1271_raw_write32
Propagate errors from wl1271_raw_write32 and request for recovery when
appropriate.
Also rename prefixes of wlcore functions which their prototypes had to
be changed.

26b5858a67 wlcore: add a debugfs entry to allow changing the sleep mode by hand
For FW debugging purposes, we may need to change the sleep mode
(aka. sleep_auth) by hand, and set it to the mode we want.  To allow
this, a debugfs entry is added.

Now we store the sleep_auth value that has been set and use that
instead of the quirk to decide whether we should enter ELP or not.

e832837bbb wlcore: don't enable BET for high basic rates
The beacon early termination is not relevant for
high basic rates, which doesn't contribute
anything to the PS and only adds unnecessary FW
work.

Enable BET only if the basic rate is less than 9
Mbps.

The dynamic PS timeout is meaningless in forced PS mode.

441101f678 wlcore: add quirk to disable ELP
ELP is a very complicated process in the firmware.  Due to its
complexity, in some early firmware revisions, the ELP feature is
disabled.  To support this cases, this patch adds a quirk that
disables ELP mode.

When ELP is not supported, do not attempt to enter ELP when requested by
the driver.

00782136b4 wlcore/wl12xx: implement chip-specific register tables
Add register tables support in wlcore, add some new IO functions to
read and write to chip-specific register and data addresses.  Move
some common register values from wl12xx to wlcore and add the
registers table to wl12xx.

7b3115f265 wl12xx/wlcore: rename wl12xx to wlcore
Rename the wl12xx driver directory to wlcore as an initial step
towards the split of the driver into wlcore and wl12xx.  We just
rename the directory first to keep git blame happy.
