These series of patches to support page scope read.

In QPIC v1, SW is needed to write EXEC_CMD register
for each Code word and collect any Status related to
that CW before issueing EXEC_CMD for next CW.

Page scope command, currently supported only for read
commands in bam mode, is truly a page mode command where
SW is required to issue EXEC_CMD only once for a page.
Controller HW takes care of Codeword specific details
and automatically returns status associated with each
CW to BAM pipe, dedicated for status deposition.
