media: staging: rkisp1: use consistent bus_info string for media_dev

Media device is using a slightly different bus_info string
"platform: rkisp1" (with a space) instead of "platform:rkisp1" used by
the rest of rkisp1 code.
This causes errors when using v4l2-util tools that uses the bus_info
string to identify the device.
