V4L/DVB (12325): Implement changing resolution on the fly for zr364xx driver

This patch implements changing resolution in zr364xx_vidioc_s_fmt_vid_cap for
zr364xx driver. This version is synced with v4l-dvb as of 20/Jul/2009. Tested
with Creative PC-CAM 880.

OBS: I had to increase MAX_FRAME_SIZE to prevent a hard crash in my notebook
(caps lock blinking) when testing with mplayer, which automatically sets
resolution to the maximum (640x480). Maybe we should add code to auto-detect
frame size to prevent this kind of crash in the future.
