This changes corrects the ioctl() operations for both the CX2388[578] analog video and MPEG video device nodes to properly and consistently support VIDIOC_G_CHIP_IDENT, VIDIOC_DBG_G_REGISTER and VIDIOC_DBG_S_REGISTER ioctl()s. This caused some ioctl() support routines to be broken out into a separate source file. Now v4l2-dbg can be used to manipulate CX2388[578] and CX23417 registers including the CX2388[57] functions handled by the cx25840 module. This was done in anticipation of developing a new v4l2_subdev for the integrated IR controller of the CX23888.
