1st set of IIO new device support, features and cleanup for 6.1

Browse Source 
This includes Nuno Sa's work to move the IIO core over to generic firmware
 properties rather than having DT specific code paths. Combined with Andy

Description:
For differential channels, this an offset that is applied
equally to both inputs. As the reading is of the difference
between the two inputs, this should not be applied to the _raw
reading by userspace (unlike _offset) and unlike calibbias
it does not affect the differential value measured because
the effect of _zeropoint cancels out across the two inputs
that make up the differential pair. It's purpose is to bring
the individual signals, before the differential is measured,
within the measurement range of the device. The naming is
chosen because if the separate inputs that make the
differential pair are drawn on a graph in their
_raw units, this is the value that the zero point on the
measurement axis represents. It is expressed with the
same scaling as _raw.

description: |
The RTQ6056 is a high accuracy current-sense monitor with I2C and SMBus
interface, and the device provides full information for system by reading
out the loading current and power.
The device monitors both of the drops across sense resistor and the BUS
voltage, converts into the current in amperes, and power in watts through
internal analog-to-digital converter ADC. The programmable calibration,
adjustable conversion time, and averaging function are also built in for
more design flexibility.
