This patch adds I2C probe function to use dvb_module_probe()
with this driver.

Hi Katsuhiro,

Thanks for patch.

What is the purpose to rework helene_set_params(_t|_s) ?
other part of this patch looks ok for me, but not tested due to lack
of spare time ;(

I'm using Socionext SC1501A (or MN88443x) ISDB-S/ISDB-T demodulator with this 
tuner. This demodulator has 1 port, and can use ISDB-S or ISDB-T exclusively.

So I think I cannot use ISDB-S features of this tuner if I use helene_attach(), 
and I cannot use ISDB-T if I use helene_attach_s() too.
