cx88: Wrong values used for HD-3000 radio mode
From: Trent Piepho <xyzzy@speakeasy.org>
After some tedious work with a logic probe and a magnifying glass, I've
determined that GPIO 7 is used to switch between the DTT7612's Sound 4.5 MHz
IF output on pin 12 and the FM 10.7MHz If output on pin 11. GPIO 2 is used to
switch the card's analog sound output from from the analog input connector to
the CX23883's audio DACs.
So, in radio mode GPIO2 = 1 and GPIO7 = 0.
Add some comments about how the HD-3000's GPIOs are connected.
Delete the vmux setting for the radio, as vmux doesn't apply to radio mode.
Also delete the lines setting unused gpio words to zero; it's not necessary as
0 is the default value for uninitialized fields.
