We have support for radio on saa7133/35/31e cards with tda8290/8275(a)
and 5.5MHz ceramic filter on the bridge chips since a while.

It was previously not tested, if this card supports it too, but the old
"ghost" radio with wrong filters doesn't work anymore.

Thanks go to Pham Thanh Nam and Laszlo Kustan for reporting it working
on that input.

V4L2 API (chapter 1.5) states that:

	Drivers must implement all input ioctls when the device has one
	or more inputs, all output ioctls when the device has one or more outputs.
	When the device has any audio inputs or outputs the driver must set the
	V4L2_CAP_AUDIO flag in the struct v4l2_capability returned by the
	VIDIOC_QUERYCAP ioctl.

So, devices without audio input should return -EINVAL.

After the i2c subdev changes the ordering of initialization changed,
causing a total loss of previous GPIO settings and a loss of DTV.
The generic firmware loading routine has now changed to preserve
GPIO values if the device is cx23885 based (safety) and I've
moved the GPIO configuration from probe() into the cx23885 init
func which is a little clearer and fixes the bug.

Replace printing to magically sized temporary buffer with use
of KERN_CONT for continual printing of eeprom registers dump.

Since deb_info is defined as dprintk, which is conditionally defined
to printk without additional parameters, meaning that deb_info is equivalent
to direct printk (without adding KERN_ facility), we can use KERN_DEBUG and
KERN_CONT in there, eliminating the need for sprintf into temporary buffer
with not easily readable/magical size.

Though it's strange, that deb_info definition uses printk without KERN_
facility and callers don't use it either.
