bb350711ec brcmfmac: handle SDIO card removal
When removing the card the driver still tries to access registers
in the device. This patch adds another state for the bus that
indicates the device is no longer reachable. This avoids errors
accessing it while cleaning up the driver.

2668b0b16c brcmfmac: initialize escan function pointer during scheduled scan
For scheduled scan results the driver does a escan to obtain BSS
details from the firmware. However, the escan uses a dynamically
determined function. This needs to be set appropriately when handling
scheduled scan results to avoid NULL pointer access.

5303626103 brcmfmac: update core reset and disable routines.
The original core reset and disable routines do not work always
on running system. These routines were updated to properly reset
a core. When module is unloaded the device is put into download
state where all necessary cores have been reset. This will make
sure the device is in idle mode after module unload.

cfg80211 still believed to be connected to an AP. The brcmfmac had
already transitioned to disconnected state during unload. This patch
adds informing cfg80211 about this transition. This will get rid of
warning from cfg80211 seen upon module unload:

fa9ffc7456 cfg80211: Add support for QoS mapping
This allows QoS mapping from external networks to be implemented as
defined in IEEE Std 802.11-2012, 10.24.9. APs can use this to advertise
DSCP ranges and exceptions for mapping frames to a specific UP over
Wi-Fi.

The payload of the QoS Map Set element (IEEE Std 802.11-2012, 8.4.2.97)
is sent to the driver through the new NL80211_ATTR_QOS_MAP attribute to
configure the local behavior either on the AP (based on local
configuration) or on a station (based on information received from the
AP).

9ecf51c583 brcmfmac: Fix hex dump for FWIL.
The debug function brcmf_dbg_hex_dump API got changed and the
information string should preferably contain a \n at the end
of the string. Update the FWIL so debug output looks better.

8141083c48 brcmfmac: Move common BCDC code in single function.
The BCDC functions query_dcmd and set_dcmd both create a msgbuf to
be sent to dongle this code is very similar and for optimisation
best put in a function.

a7cdd821e3 brcmfmac: reduce function parameters in sdio send/receive calls
The SDIO send and receive functions in bcmsdh.c are always called
with the same parameters. For the driver there is no use-case
to call them otherwise so remove those parameters from function
prototypes.
