msm: Create shadow files under /sys/kernel/ipv4

The TCP delayed ack parameters can be configured from user space
application which runs with non-root credentials and does not have
direct write access to /proc entries. This commit creates shadow
files under /sys/kernel/ipv4 which maps to /proc/sys/net/ipv4.

msm: kgsl: Update calculation for graphics IOMMU context IDs

Calculate graphics IOMMU context IDs using the 'label' property of
the device tree node of that context. Context IDs are independent
of the register addresses of the SMMU device and its contexts, which
change for every target.

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 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.

msm: kgsl: Protect CP_STATE_DEBUG_INDEX

Put CP_STATE_DEBUG_INDEX and CP_STATE_DEBUG_DATA under protection
to keep it from being written from an IB1. Doing so however opens
up a subtle "feature" in the microcode: memory read opcodes turn off
protected mode in the microcode to do the read and then turns it
back on regardless of the initial state. This is a problem if the
memory read happens while protected mode is turned off and then we
try to access a protected register which then complains and goes boom.

To account for this irregularity explicitly turn back off protected
mode in all the places where we know this will be a problem.
