stb0899_read_ber() takes 500ms (half a second!) to deliver the current
BER value. Apparently it takes 5 subsequent readings, with a 100ms pause
between them (and even before the first one). This is a real performance
brake if an application freqeuently reads the BER of several devices.
The attached patch reduces this to a single reading, with no more pausing.
I didn't observe any negative side effects of this change.

MPIS based STBs running 3.x kernels and the Enigma2 OS are not able to tune
DVB-T channels with the PCTV 290e using the current cxd2820r driver.
DVB-T2 channels instead work properly.
This patch fixes the problem by changing the condition to break out from the
wait lock loop in the "search" function of the cxd2820r demodulator from
FE_HAS_SIGNAL to FE_HAS_LOCK.
As a consequence, the "search" function of the demodulator driver now returns
DVBFE_ALGO_SEARCH_SUCCESS only if the frequency lock is successfully acquired.
This behavior seems consistent with other demodulator drivers (e.g. stv090x,
hd29l2, stv0900, stb0899, mb86a16).
This patch has been successfully tested with DVB-T and DVB-T2 signals,
on both PC and the mipsel STB running Enigma2.
No apparent side effect has been observed on PC applications like Kaffeine.
DVB-C is not available in my country so it's not tested.

af9033: implement read_ber and read_ucblocks functions. Version 2 of patch that
reflects my findings on the behaviour of abort_cnt, err_cnt and bit_cnt:
- bit_cnt is always 0x2710 (10000)
- abort_cnt is between 0 and 0x2710
- err_cnt is between 0 and 640000 (= 0x2710 * 8 * 8)
in the current implementation BER is calculated as the number of bit errors per
processed bits, ignoring those bits that are already discarded and counted in
abort_cnt, i.e. UCBLOCKS.

au8522_dig.o and au8522_decoder.o function independentantly
of each other, each for a different hardware function using
a different software subsystem api, each with its own set
of subsystem module dependencies.
Since these drivers do not depend on each other, and it is
in fact possible to build hardware designs using one function
and not the other, lets split this module into two, allowing
system integrators to enable the hardware without dragging in
undesired dependencies.

stb0899: fix the limits for signal strength values
stb0899_read_signal_strength() adds an offset to the result of the table lookup.
That offset must correspond to the lowest value in the lookup table, to make sure
the result doesn't get below 0, which would mean a "very high" value since the
parameter is unsigned.
'strength' and 'snr' need to be initialized to 0 to make sure they have a
defined result in case there is no "internal->lock".
