[media] m88ts2022: change parameter type of m88ts2022_cmd
It is driver internal function and does not need anything from
frontend structure. Due to that change parameter type to driver
state which is better for driver internal functions.
Also remove one unused variable from state itself.

[media] m88ts2022: clean up logging
There is no need to print module name nor function name as those
are done by kernel logging system when dev_xxx logging is used and
driver is proper I2C driver.

[media] m88ts2022: rename device state (priv => dev)
foo_dev seems to be most correct term for the structure holding data
of each device instance. It is most used term in Kernel and also
examples from book Linux Device Drivers, Third Edition, uses it.

[media] m88ts2022: fix 32bit overflow on filter calc
Maximum satellite symbol rate used is 45000000Sps which overflows
when multiplied by 135. As final calculation result is fraction,
we could use mult_frac macro in order to keep calculation inside
32 bit number limits and prevent overflow.
Original bug and fix was provided by Nibble Max. I decided to
implement it differently as it is now.

[media] m88ts2022: reimplement synthesizer calculations
Used synthesizer is very typical integer-N PLL, with configurable
reference frequency divider, output frequency divider and of
course N itself. Most common method to calculate values is first
select output divider, then calculate VCO frequency and finally
calculate PLL N from VCO frequency. Do it that way.
Also make some cleanups for filter logic and signal strength.
