-Read whole info block in one i2c transaction.
-And then re-read the matrix size after applying pdata config, since
-it may have changed.
-Note, however, that the matrix x & y size are just displayed for
-information purposes.  They aren't actually used by the driver itself.
-
-Also, parse and info print the firmware major and minor version numbers.
+It isn't sent, nor checked anyway, so don't bother reading it.
