This patch fixes the tuning issue I was having.
Tuning to 482MHz was impossible. Now this driver works
as expected for me.

I also removed a line that set the tuner access gate to disabled
(register 0x62), while a few writes later it is re-enabled.
This doesn't impact the correct working of the driver for me.

Carl, do you confirm that these changes don't have any impact
when you use the driver on another frequency?
I can only test 482MHz as this is the only channel in my
