media: imx-jpeg: Leave a blank space before the configuration data

Browse source

[ Upstream commit 6285cdea19 ]

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
