V4L/DVB (6965): tda18271: fix analog tuning regression caused by earlier changeset
An earlier patch, "tda18271: fail table lookups if frequency is out of range" broke analog support on certain hardware. This patch fixes that problem, by allowing the RF_CAL byte to be set to the maximum value, in cases of the frequency being out of range.
