On the s5h1409 demod, the IF frequency for VSB is limited to 44 / 5.38 MHz.
Hardcode VSB IF frequency within the driver to 44 / 5.38 MHz.
QAM IF frequency remains configurable via attach-time configuration.

patch extends the lookup tables to ensure correct values are being
returned.

This patch adds support for the Samsung S5H1409 demodulator, also known
as the Conexant CX24227 demodulator. 8VSB mode has been tested and QAM
has been implemented based on the spec, although it's untested.
The S5H1409 / CX24227 appears on various Hauppauge boards.
