media: ipu-bridge: use IPU_MAX_PORTS for bridge instead of CIO2_NUM_PORTS

Before bridge driver use CIO2_NUM_PORTS as the maximum supported CSI2 port
number. Current bridge driver is moved out of ipu3, so define a new macro
in ipu bridge for all IPUs instead of including CIO2 definition.
This patch also removes the ipu3-cio2.h inclusion in ipu-bridge.h.
