atomisp: lc898211: add temporary code for early development stage

BZ: 27947

lc898211 driver is still in early development stage as 3A library tuning
doesn't work well yet. This patch adds debugging messages and 8-bit to
10-bit conversion for compatibility with current 3A library.

This patch must be reverted once 3A library support is implemented.
