The firmware hang issue is not seen very often,
though it is still seen sometimes (once in 12
hours in local tests). The changes in the driver
,to interrupt the firmware, are needed when we
detect that firmware is stuck and when the host
queues are full and we begin to drop packets.
This is to ensure that the firmware does not
miss any PPA_RDY interrupts to cause the firmware
restart dont miss PPA_READY interrupt for SC2

AR934x v1.3 no longer needs the DCU backoff reduction workaround for
preventing rx overruns, but in turn needs the number of usable Tx
buffers to be reduced slightly.

If a local bus timeout has been detected, the host interface needs to be
reset to clear the errors. AR934x uses a different synchronous interrupt
bit to indicate this, so the check needs to be fixed.

Do not subtract spur power from noise floor on this chip, as it can lead

Unfortunately, advertising P2P_DEVICE support was a little
premature, a number of issues came up in testing and have
been fixed for 3.10. Rather than try to backport all the
different fixes, disable P2P_DEVICE support in the drivers
using it.

as it can't support P2P operation w/o P2P Device.

Some of the key differences between SD8897 and older chipsets
are as follows:
a) sdio mpa_rx and mpa_tx ports have been increased from 16 to 32
b) Same is the case with read/write bitmap that one receives from
mpa_reg read
c) aggregation packet count doubled from 8 to 16
d) Most of key reg addresses are changed
e) There is a separate command or control port
f) Now command rx/tx_done have new interrupts
1. 'supports_sdio_new_mode' flag is added to handle (a) and (b).
2. (c) and (d) are taken care of by filling chip specific
information in global structurei (mwifiex_sdio_sd8897).
3. For older chipsets, port 0 was cmd port and port 1->15 were
data port. Therefore we had CTRL_PORT_MASK to differentiate
port type. Now these changes are under 'has_control_mask' flag.

There are some macros defined for multiport aggregation
calculations. As we may need to add some more code to
accomodate new chipsets, we will change them to inline
functions. Also, use dynamic allocation for Rx buffer array.
