[media] dvb-frontend: add core support for tuner suspend/resume
While several tuners have some sort of suspend/resume
implementation, this is currently mangled with an optional
.sleep callback that it is also used to put the device on
low power mode.
Not all drivers implement it, as returning the driver from
low power may require to re-load the firmware, with takes
some time. Also, some drivers may delay it.
So, the more coherent is to add two new optional callbacks
that will let the tuners to directy implement suspend and
resume callbacks if they need.

media: core: Don't use i2c_client->driver
The 'driver' field of the i2c_client struct is redundant and is going to be
removed. The results of the expressions 'client->driver.driver->field' and
'client->dev.driver->field' are identical, so replace all occurrences of the
former with the later.

[media] tuner-core/simple: get_rf_strength can be tuner mode specific
The get_rf_strength op in tuner-simple is valid only for the radio mode.
But due to the way get_signal in analog_demod_ops was designed it would
overwrite the signal value with a bogus value when in TV mode.
Pass a pointer to the signal value instead, and when not in radio mode
leave it alone in the tuner-simple.
This broke in commit 030755bde42bbed133182b0ece7c7a9c759478e8
(tuner-core: call has_signal for both TV and radio) in kernel 3.6. Before
that this was working correctly. That commit did the right thing, but what
wasn't realized at the time was that tuner-simple should have been updated
as well to restrict setting the signal strength to the radio mode only.

The get_afc op in tda9887 is valid only for the radio mode.

overwrite the afc value with a bogus value when in TV mode.
Pass a pointer to the afc value instead, and when not in radio mode

This broke a long time ago in 2.6.19 when the get_afc op was introduced.
Before that the afc was only set for radio mode in the tda9887.

[media] tuner-core: Change config from unsigned int to void *
config looks like a hack that was added to tuner-core to allow some
configuration of TDA8290 tuner (it's not used by any other driver).
But with the new configuration options of tda8290 driver (no_i2c_gate
and std_map), it's no longer sufficient.
Change config to be void * instead, which allows passing tuner-dependent
config struct to drivers.
Also update saa7134 driver to reflect this change (no other driver uses this).

[media] tuner-core: don't set has_signal/get_afc if not supported
If the tuner frontend does not support get_rf_strength, then don't set
the has_signal callback. Ditto for get_afc.
Both callbacks overwrite the signal and afc fields of struct v4l2_tuner
but that should only happen if the tuner can actually detect this. If
it can't, then it should leave those fields alone so other subdevices
can try and detect the signal/afc.
This fixes the bug where the au8522 detected a signal and then tuner-core
overwrote it with 0 since the xc5000 tuner does not support get_rf_strength.

[media] tuner-core: map audmode to STEREO for radio devices
Fixes a v4l2-compliance error: setting audmode to a value other than mono
or stereo for a radio device should map to MODE_STEREO.
The spec specifies that for radio devices only mono and stereo audmodes are
valid. If the user specifies another audmode in v4l2_tuner, then that should
be mapped to valid audmode. That didn't happen here.
Note that tuner drivers might decide to limit the possible audmode even
further if it only supports mono. In that case the tuner driver can set
audmode to mono. However, that new value wasn't copied back to t->audmode,
and that has been fixed as well in this patch.
