Original plan was to implement driver as one file per used demod
standard (mn88472_c.c, mn88472_t.c and mn88472_t2.c). However, that
plan was a mistake as driver code differences are so small between
different standards. Due to that rename this file and implement all
the needed functionality to that file.

Previous patch changes used signal strength firmware register from
0x800048 to 0x80004a in case of AF9033/AF9035 chip. In practice
reported values were running upside-down, when RR strength increases
reported value decreases and vice versa. That is because of 0x80004a
returns values that are dBm scale, but negative RF strength dBm
returned as positive number.

0x800048 returns 0-100, like percentage
0x80004a returns 0-255 dBm, without a negative sign

So restore old measurement now.

M88RS6000 is the integrated chip, which includes tuner and demod. Its
internal demod is similar with M88DS3103 except some registers
definition.

The main different part of this internal demod from others is its
clock/pll generation IP block sitting inside the tuner die. So clock/pll
functions should be configed through its tuner i2c bus, NOT its demod
i2c bus.

The demod of M88RS6000 need the firmware: dvb-demod-m88rs6000.fw

This code is needlessly complicated and checkpatch.pl complains that we
go over the 80 characters per line limit.

If we flip the "if (!lock) {" test to "if (lock) return;" then we can
remove an indent level from the rest of the function.

We can add two returns in the "if (state->srate >= 10000000) {"
condition and move the else statement back an additional indent level.

There is another "if (!lock) {" check which can be removed since we have
already checked "lock" and know it is zero at this point.  This second
check on "lock" is also a problem because it sets off a static checker
warning.  I have reviewed this code for some time to see if something
else was intended, but have concluded that it was simply an oversight
and should be removed.  Removing this duplicative check gains us an
third indent level.

The Tevii S480 outputs 18V on startup for the LNB supply voltage and does not
automatically power down. This blocks other receivers connected
to a satellite channel router (EN50494), since the receivers can not send the
required DiSEqC sequences when the Tevii card is connected to a the same SCR.

This patch switches off the LNB supply voltage on initialization of the frontend.

This patch partially reverts 0fb220f2. What happened is
that the conversion of debug messages to use pr_debug() was a
bad idea, because one needing to debug would need to both
enable debug level via a modprobe parameter, and then to
enable the dynamic printk's.

So, for now, let's use printk() directly at dprintk().
