media: v4l: fwnode: Use a less clash-prone name for MAX_DATA_LANES macro

Browse Source 
Avoid using a generic name such as MAX_DATA_LANES in a header file widely
included in drivers. Instead, call it V4L2_FWNODE_CSI2_MAX_DATA_LANES.

Fixes: 4ee236219f6d ("media: v4l2-fwnode: suppress a warning at OF parsing logic")
