Added code to detect the XC4100 chip, which is presumably an analog-only
"value" version of the XC4000. It is not sure, however, if any devices
using this have actually been produced and sold, so the patch may be
unneeded.

This patch causes the tuner reset command to be ignored in the firmware
code, since this only happens when the BASE/INIT1 firmware is loaded by
check_firmware(), and in that case check_firmware() already calls the
reset callback before starting to load the firmware.

This patch implements setting the registers in xc4000_set_params()
and xc4000_set_analog_params(). A new register is defined which enables
filtering of the composite video output (this is needed to avoid bad
picture quality with some boards).
