Support for tuners with i2c addresses >= 0x65 is dropped since no tuners
with addresses in the range 0x65-0x6f have been found.

This patch removes addresses 0x65-0x6f from the list of tuner probe addresses,
it removes the kernel warning that warned if addresses in this range appeared,
and it removed a hack for the cx88 that is no longer needed now that the
tuner address range is reduced.
