dt-bindings: hwmon/pmbus: Add Infineon xdp730

Browse Source 
Add documentation for the device tree binding of the XDP730 eFuse.
Rename node to efuse to accurately reflect its hardware function.

The XDP720 is an eFuse with integrated current sensor and digital
controller. It provides accurate system telemetry (V, I, P, T) and
reports analog current at the IMON pin for post-processing.
The XDP720 and XDP730 are PMBus-compliant digital eFuse controllers
with an integrated current sensor. They provide accurate system
telemetry (V, I, P, T) and report analog current at the IMON pin for
post-processing.
Datasheet:
https://www.infineon.com/assets/row/public/documents/24/49/infineon-xdp720-001-datasheet-en.pdf
Both parts share the same PMBus register map and direct-format
coefficients; they differ in the GIMON gain step exposed via the
TELEMETRY_AVG register (bit 10) and in the VDD_VIN pin number
(XDP720: pin 9, XDP730: pin 20).
