is hybrid driver implementing both V4L2 and DVB ops.

f8b9b871f8 [media] e4000: various small changes
* Rename device state from 's' to 'dev'.
* Move single include to driver private header.
* Change error handling type of each function to one I tend use
nowadays.
* Remove dummy register write from init. Even Windows driver does this
multiple times remove it as I have never seen any I2C errors.
* Define I2C client pointer for each function and use it.
* Do not clean tuner ops during driver remove - not needed.
* Disable sysfs device bind / unbind. We are not allowed manually
bind / unbind device from the driver currently.
* Rename some other variables.

0e3a71c374 [media] e4000: revise synthesizer calculation
Update synthesizer calculation to model I prefer nowadays. It is
mostly just renaming some variables to ones I think are most standard.
Also add 'schematic' of synthesizer following my current understanding.

bd428bbc75 [media] e4000: convert to Regmap API
That comes possible after driver was converted to kernel I2C model
(I2C binding & proper I2C client with no gate control hack). All
nasty low level I2C routines are now covered by regmap.
