media: rockchip: rga: align stride to 4 bytes

Browse source

Add an alignment setting to rga_hw to set the desired stride alignment.
As the RGA2 register for the stride counts in word units, the code
already divides the bytesperline value by 4 when writing it into the
register. Therefore fix the alignment to a multiple of 4 to avoid
potential off by one errors due from the division.
