hwmon: (pmbus/vt7505) Add driver for Analog Devices MAX16545/MAX16550 and Volterra VT7505

Add a PMBus driver for the Analog Devices MAX16545 and MAX16550, and the
Volterra VT7505 controllers. The driver reports input/output voltage,
input/output current, input power and temperature over PMBus. All values
use the direct data format. Peak input voltage, output voltage, output
current, input power and temperature readings are exposed and can be
reset.

The reported current and power depend on the external current-report
resistor connected to the ILOAD pin, which can be provided through the
"adi,rload-ohms" device tree property.

On the MAX16550 and VT7505, the severe-OCP deglitch time can optionally
be configured with the "adi,ocp-severe-filter-us" device tree property.
When omitted, the existing hardware setting is left unchanged.
