ODROID-C5: arm64/dts: Enable vdin1 node

vdin1 node is removed in this commit :
  [fb2690f09 ODROID-C5: arm64/dts: Removed unused nodes.]

However, this node is required to support screen capture using
/dev/video12 node which is related with amlvideo2 driver.

Without this, driver couldn't acquire the memory space to store frame data,
and it returns EBUSY error when VIDIOC_STREAMON is performed by ioctl.
