media: imx-jpeg: Leave a blank space before the configuration data
[ Upstream commit
6285cdea19daf764bf00f662a59fc83ef67345cf ]
There is a hardware bug that it will load
the first 128 bytes of configuration data twice,
it will led to some configure error.
so shift the configuration data 128 bytes,
and make the first 128 bytes all zero,
then hardware will load the 128 zero twice,
and ignore them as garbage.
then the configuration data can be loaded correctly
