With the introduction of dynamic routing between HDMI and AFE entities to TXA, checking which TX the function is operating on is not meaningful anymore. To fix this, store the subdevice of the source providing video data to the CSI-2 TX in the 'struct adv748x_csi2' representing the TX and check on it.
