schemas: legacy: deduplicate XDPE152C4, XDPE152C4D

This is likely a typo as the PSUSensor in dbus-sensors only supports
XDPE152C4. The 'D' is for 'Version Control', and i assume no daemon
makes use of the difference (if there is any).

The only affected configuration is nf5280m7_baseboard.json
The contributor of the adjusted configuration is added for review.

Tested: Schema Validator Pass
