DIAG maintains mask info in a buffer. This buffer is parsed
using a structure. Recently this structure was modified to add
another member. Now, the parsing code has to change to account
for this new member, otherwise, the parsing is incorrect and
misses certain log codes.
Also updated log codes with the latest on modem.

From 8960 onwards, application processor handles master diag. Other
slave processors can come up on different time. This change will
update each slave processor with latest mask info when it comes up.
Also each time, any PC tool tries to change masks, application processor
will propagate this new mask info to the peripherals. Now, this mask
updation tasks need to be delayed. Hence, such tasks cannot be put on
regular work queue. Thus, this change also adds a new work queue for such
tasks.
This feature also requires latest build time masks on apps processor. Thus,
updated the build time masks as well.

Allow automatic power management by the USB core by enabling
autosuspend in the DIAG Bridge driver. This allows the MDM device
to be suspended and draw minimal power when idle.
In the diagfwd_hsic driver, register suspend and resume callbacks
to know when to temporarily halt queuing read or write requests to
the bridge which would otherwise prevent the HSIC device from
triggering an autosuspend.
Similarly, close the bridge when the USB cable is disconnected to
signify that it is done using it, or else there would forever be a
pending read or write on the bridge that would keep the HSIC active.
Revert allocation flags in diag_bridge_read() and diag_bridge_write()
to GFP_KERNEL, as they now can only be called in process context.

DIAG driver maintains a table for all registrations by remote
peripherals and user space applications. In certain cases, the
number of registrations can exceed table capacity. Thus, diag
re-allocates the table memory, to fit in all registrations.
This re-allocation stops at a threshold, even if requirement
is greater than threshold.
In such a corner case, if the requirement is greater than threshold,
then the mutex might remain locked after filling the table upto full
capacity. Adding unlocking condition to release mutex in such cases.

During initialization, there is a violation in writing to

Trustzone marks certain registers as read-only.
This change fixes the issue by writing to registers only

DIAG driver talks to peripheral processors over SMD channels.
Sometimes, SMD channel can have a partial packet and if diag
reads it, it can mistake them as garbled packets. With this
change, if the packet is incomplete, diag will not read it
and wait until the packet is complete.
This approach will work, as long as, peripheral is sending packets
less than 1000 bytes. Currently even the peripheral is limited to
sending packets upto 1K bytes, so this limitation is fine.
Also fix potential memory allocation failure and unnecessary
reading from SMD channels.

DIAG driver communicates to peripherals over SMD channels. It parses
data read and then takes appropriate actions. Sometimes, SMD can pass
corrupted data and cause DIAG driver to crash. Adding checks around
data will prevent such crashes.

PC tools send various polling commands to target to detect its
presence. Initially modem used to respond to all pollings. However,
with new targets, we have applications processor as master as well
as subsystem restart. Due to these new features, modem does not respond
all the time. This change implements a new mechanism to respond to
polling.
The DIAG driver maintains a flag variable to keep track of any polling
command registered by a remote peripheral. As long as any polling command
is present, diag driver ignores a special polling request. If no peripheral
has registered for any polling at all, then diag responds to this special
polling request.

DIAG provides packet request/response service. A PC tool
can send a request and receive response from an app on
phone. In case, app is not running, the phone should return
an error response, which is almost same length as request.
A buffer overrun can happen, if the request is too huge. Thus,
adding a check to prevent buffer overrun.
