[PATCH V4 0/3] i2c: qup: Some misc fixes

[Sricharan R <sricharan@codeaurora.org>]

One for fixing the bug with CONFIG_DEBUG_SG enabled, another
to suspend the transfer for all errors instead of just for NACK
and one for correcting the wrong initial value for index variable.

[V4] Added little more description to patch#1 and split a
     change in to a new patch.
 
[V3] Added more commit description. Return more appropriate
     error codes for NACK and other bus errors. Corrected
     other bus errors handling procedure for dma mode as well.
     Removed the dev_err log for NACKs.

[V2] Removed the use of unnecessary variable assignment.

Kept the reviewed and Tested by tag for patch#1,
as there was no code change.

Depends on patch[1] for the error handling to be complete.
