* ad53xx: voltage_to_mu() validation & documentation (closes#1443, #1444)
The voltage input (float) is checked for validity. If we need more
speed, we may want to check the DAC-code for over/underflow instead.

* ad53xx documentation: voltage_to_mu is only valid for 16-bit DACs

* AD53xx: add voltage_to_mu method (closes#1341)

* ad53xx: improve voltage_to_mu performance
Interger comparison is faster than floating point math.

Several core device drivers maintain a copy of some device state.
Since this copy is not transferred between experiments this backing state
can be different from device state when a new experiment is started.
This commit adds support for injecting initial backing state into
experiments via the device database and sets initial backing state where
known.
ad53xx (zotino): spi2 xfer_duration
novogorny: pgia gains
sampler: pgia gains, spi2 pgia and adc xfer_duration
suservo: pgia gains, spi2 pgia xfer_duration
urukul: cpld cfg (partial: rf_sw), attenuator register
spi2: div/length for xfer_duration
close#1003
* Replace ad5360 driver with a ad53xx driver, designed to have a nicer interface
Add Zotino driver and add to opticlock target for Kasli
Test Zotino on hw:
- Verify all timings on the hardware with a scope
- Verify that we can correctly set and read back all registers in a loop (checks for SI and driver issues)
- check we can set LEDs correctly
- check calibration routine + all si unit functions with a good DVM
- look at DAC transitions on a scope (while triggering of a TTL) on persist to check there are no LDAC glitches etc
To do: update examples and e.g. KC705 device db.
