[media] media: ths7353: add support for ths7353 video amplifier

The patch adds support for THS7353 video amplifier.
The the THS7353 amplifier is very much similar to the
existing THS7303 video amplifier driver.
This patch appropriately makes changes to the existing
ths7303 driver and adds support for the THS7353.
This patch also adds V4L2_IDENT_THS7353 for the THS7353
chip and appropriate changes to Kconfig file for building.

(all unshown fields are filled with zeros)
Of course, transmission mode being a negative number is wrong.
So, we need to take a deeper look on it.
With the debugfs patches applied, it is possible to see that, instead
of filling StatisticsType with 5, and FullSize with the size of the
payload (this is what happens with sms2270 and firmware 8.1),
those fields are also initialized with zero:

TransmissionMode = -64 ModemState = 0 GuardInterval = 0
SystemType = 0 PartialReception = 0 NumOfLayers = 0
SmsToHostTxErrors = 0
The data under "TransmissionMode" varies according with the signal,
and it is negative. It also matches the value for InBandPwr when
the tuner is on DVB-T (ok, signal doesn't lock, but the power level
should be about the same with the antena fixed, and measured at about
the same time).
So, there's a very high chance that, when StatisticsType is zero, the
signal strength is at the same position as Transmission Mode.
So, discard all other parameters, and provide only signal/rf lock and
