V4L/DVB (6653): Add support for the DViCO FusionHDTV NANO2 w/ZL10353 and firmware

Add support for the DViCO FusionHDTV DVB-T NANO with zl10353 demodulator and
firmware in ROM on the device.

Again, this is based on the great work of Mike Krufky with my modifications
to use the in-tree XC2028 driver.
