Add support for devcoredump in the driver. This helps in capturing
the snapshot of DDR memory that firmware uses in the event of a
firmware assert which aids in firmware debug.

First patch in the series adds the coredump infrastructure to the
driver but no hardware support is included. Second one in the series
adds the support to capture MSA memory during firmware assert on
WCN6750.
