wcnss: Configure WLAN MAC addr through user control interface

wcnss userspace service will use user control interface to configure
certain parameters required by wcnss driver. This interface is required
to configure the WLAN MAC address. These parameter was earlier written
thru module parameters from wcnss service, however that required the
wcnss userspace daemon to have the root permission.

debugging purpose.

wcnss: Increse the log level for WCNSS register dump

WCNSS register dump is only performed during WCNSS fatal errors such as
WDI timeout leading to SSR or WDOG bite scenarios. So these register
dumps should always be logged to provide the only information available
to debug these fatal errors.

msm: wcnss: Add the support to access IRIS registers using bit-bang

During cold boot, if firmware watchdog bite happens, WCNSS platform driver
will try to log Pronto registers, but in some cases it cannot access them
since there is no clock on Pronto. Add the support to log IRIS registers
using bit-bang in order to debug this issue.

msm_bam_rmnet: Fix packet corruption due to QoS

Remove the QoS header added at the beginning of the
SKB (If QoS is enabled) in case of a failure to send
a packet to bam_dmux in order to avoid a possible loop
that adds QoS headers on each failure which will cause
a packet corruption.

net: do not pretend FRAGLIST support

[ Upstream commit 28e24c62ab3062e965ef1b3bcc244d50aee7fa85 ]

Few network drivers really supports frag_list : virtual drivers.

Some drivers wrongly advertise NETIF_F_FRAGLIST feature.

If skb with a frag_list is given to them, packet on the wire will be
corrupt.

Remove this flag, as core networking stack will make sure to
provide packets that can be sent without corruption.

msm: subsystem_restart: Add notification to indicate powerup failure

Currently, if powering on a subsystem during restart fails, a
kernel panic is trigerred immediately.
Instead, send a 'powerup failure' notification to the drivers
that have registered for notifications regarding the subsystem.
The drivers can then do the necessary cleanup/logging before a
kernel panic is triggered.

wcnss: Log debug registers when receives certain notification

If powering on a subsystem during restart fails, SSR framework will send
a "powerup failure" notification to the subsystem. Add the support that
WCNSS platform driver will register to listen the notifications and if
receives "powerup failure" notification, it will log the debug registers.

wcnss: add API to check if wcnss is undergoing an SSR

Wlan driver should not read registers from wcnss or
try to communicate with the chip when it is undergoing
a subsystem-restart. Added an API with the wcnss platform
driver to check if ssr is in progress, this API will be
used by the wlan driver to protect register access and
other prohibited operations.
