[media] dvb_frontend: Don't call get_frontend() if idle

If the frontend is in idle state, don't call get_frontend.

Calling get_frontend() when the device is not tuned may
result in wrong parameters to be returned to the
userspace.

I was tempted to not call get_frontend() at all, except
inside the dvb frontend thread, but this won't work for
all cases. The ISDB-T specs (ABNT NBR 15601 and ARIB
STD-B31) allow the broadcaster to dynamically change the
channel specs at runtime. That means that an ISDB-T optimized
application may want/need to monitor the TMCC tables, decoded
at the frontends via get_frontend call.

So, let's do the simpler change here.

Eventually, the logic could be changed to work only if
the device is tuned and has lock, but, even so, the
lock is also standard-dependent. For ISDB-T, the right
lock to wait is that the demod has TMCC lock. So, drivers
may need to implement some logic to detect if the get_frontend
info was retrieved or not.

[media] xc4000: add support for signal strength measures

In xc4000 chipsets real signal and noise level is stored in register
0x0A and 0x0B,so we can use those registers to monitor signal strength.

I tested this patch on 2 different cards Leadtek DVR3200 and DTV2000H
Plus, both with same results, I used special antenna hubs (toner 4x, 6x,
8x and 12x) with mesured signal lost, both registers are in dB value,
first represent signal with limit value -113.5dB (should be -114dB) and
exactly match with test results. Second represents noise level also in
dB and there is no maximum value, but from tests we can drop everything
above 32dB which tuner realy can't use, signal was usable till 20dB
noise level.

In digital mode we can take signal strength but sadly noise level is not
relevant and real value is stored in demodulator for now just zl10353,
also digital mode is just for testing, because it needs changing other
parts of code which reads data only from demodulator.

In analog mode I was able to test only FM radio, signal level is not
important, it says something about cable and hub losts, but nothing
about real quality of reception, so even if we have signal level at
minimum 113dB we can still here radio, because of that it is displaied
only in debug mode, but for real signal level is used noise register
which is again very accurate, radio noise level was betwen 6-20dB for
good signal, 20-25dB for medium signal, and above 25dB signal is
unusable.

For now real benefit of this patch is only for FM radio mode.

mb86a20s: Add a few more register settings at the init seq

Some time ago, Manoel sent us a patch adding more stuff
to the init sequence. However, his patch were also doing
non-related stuff, by changing the init logic without
any good reason. So, it was asked for him to submit a
patch with just the data that has changed, in order to
allow us to better analyze it.

As he didn't what it was requested, I finally found some
time to dig into his init sequence and add it here.

Basically, new stuff is added there. There are a few changes:

1) The removal of the extra (duplicated) logic that puts
   the chip into the serial mode;
2) Some Viterbi VBER measurement init data was changed from
   0x00 to 0xff for layer A, to match what was done for
   layers B and C.

None of those caused any regressions and both make sense
on my eyes.

The other parameters additions actually increased the
tuning quality for some channels. Yet, some channels that
were previously discovered with scan disappered, while
others appeared instead. This were tested in Brasilia,
with an external antena.

At the overall, it is now a little better. So, better to
add these, and then try to figure out a configuration that
would get even better scanning results.

URBs allocated with usb_alloc_urb() are allocated from DMA-coherent

Therefore, we mark all URBs allocated with usb_alloc_urb() with the
URB_NO_TRANSFER_DMA_MAP transfer_flags, so that the USB core does not
do dma_map_single()/dma_unmap_single() on those buffers.
