In the new API implementation the driver does not keep the internal and
external debug configurations in separate structs so the last
configuration that is loaded overrides the previous ones (this is true
only in some of the TLVs e.g. the buffer allocation TLV).
Load the external configuration after the internal is loaded so that
user configuration will override the default coming with the FW.

With shallow buffer size, certain BT devices have active
A2DP flow control to fill buffer frequently. If the slot
is not at BT side, data can't be sent successfully to BT
devices, and will cause audio glitch.

To resolve this issue, this commit splits TUs into 4-slots
instead of 2-slot for all of the A2DP related coexistence
strategies. That makes BT have higher opportunity to fill
the A2DP buffer in time, and the audio quality could be
more stable and smooth.

In this step, the read/write routines for the descriptors are converted

As a first step in the conversion, the macros that set the RX and TX
descriptors are converted to static inline routines, and the names are
changed from upper to lower case. To minimize the changes in a given
step, the input descriptor information is left as as a byte array
(u8 *), even though it should be a little-endian word array (__le32 *).
That will be changed in the next patch.

We set WL1271_FLAG_IRQ_RUNNING in the beginning of wlcore_irq(), but clear
it before interrupt handling is done in wlcore_irq_locked().

Let's move the clearing to the end of wlcore_irq() where it gets set,
and remove the old comments about hardirq. That's no longer the case as
we're using request_threaded_irq().

Note that the WL1271_FLAG_IRQ_RUNNING should never race between the
interrupt handler and wlcore_runtime_resume() as because of autosuspend
timeout we cannot enter idle between wlcore_irq_locked() and the end of
wlcore_irq().

The RTL8723BU suffers the wifi disconnection problem while bluetooth
device connected. While wifi is doing tx/rx, the bluetooth will scan
without results. This is due to the wifi and bluetooth share the same
single antenna for RF communication and they need to have a mechanism
to collaborate.

BT information is provided via the packet sent from co-processor to
host (C2H). It contains the status of BT but the rtl8723bu_handle_c2h
dose not really handle it. And there's no bluetooth coexistence
mechanism to deal with it.

This commit adds a workqueue to set the tdma configurations and
coefficient table per the parsed bluetooth link status and given
wifi connection state. The tdma/coef table comes from the vendor
driver code of the RTL8192EU and RTL8723BU. However, this commit is
only for single antenna scenario which RTL8192EU is default dual
antenna. The rtl8xxxu_parse_rxdesc24 which invokes the handle_c2h
is only for 8723b and 8192e so the mechanism is expected to work
on both chips with single antenna. Note RTL8192EU dual antenna is
not supported.
