[media] v4l: add new tuner types for SDR
Define tuner types V4L2_TUNER_ADC and V4L2_TUNER_RF for SDR usage.
ADC is used for setting sampling rate (sampling frequency) to SDR
device.
Another tuner type, named as V4L2_TUNER_RF, is possible RF tuner.
Is is used to down-convert RF frequency to range ADC could sample.
Having RF tuner is optional, whilst in practice it is almost always
there.
Also add checks to VIDIOC_G_FREQUENCY, VIDIOC_S_FREQUENCY and
VIDIOC_ENUM_FREQ_BANDS only allow these two tuner types when device
type is SDR (VFL_TYPE_SDR). For VIDIOC_G_FREQUENCY we do not check
tuner type, instead override type with V4L2_TUNER_ADC in every
case (requested by Hans in order to keep functionality in line with
existing tuners and existing API does not specify it).
Prohibit VIDIOC_S_HW_FREQ_SEEK explicitly when device type is SDR,
as device cannot do hardware seek without a hardware demodulator.

[media] drx-j: get rid of drxj_ctrl()
With this change, we finally got rid of all abstraction
layers on this driver.
This patch also fixes the LNA GPIO settings, as the original
code were using a wrong control name for it.
This patch exposes the several functions that aren't used.
Some of them are related to analog demod that might be
used some day, but others will likely never be needed, as
they don't fit on Linux media APIs.
Latter patches will clean up this mess.

[media] em28xx: implement em28xx_usb_driver suspend, resume, reset_resume hooks
Implement em28xx_usb_driver suspend, resume, and reset_resume hooks.
These hooks will invoke em28xx core em28xx_suspend_extension() and
em28xx_resume_extension() to suspend and resume registered extensions.
Approach:
Add power management support to em28xx usb driver. This driver works in
conjunction with extensions for each of the functions on the USB device
for video/audio/dvb/remote functionality that is present on media USB
devices it supports. During suspend and resume each of these extensions
will have to do their part in suspending the components they control.
Adding suspend and resume hooks to the existing struct em28xx_ops will
enable the extensions the ability to implement suspend and resume hooks
to be called from em28xx driver. The overall approach is as follows:
-- add suspend and resume hooks to em28xx_ops
-- add suspend and resume routines to em28xx-core to invoke suspend
and resume hooks for all registered extensions.
-- change em28xx dvb, audio, input, and video extensions to implement
em28xx_ops: suspend and resume hooks. These hooks do what is necessary
to suspend and resume the devices they control.
