drivers: rtc: rv3032: Restore configuration of backup reg

jacobschloss · aescolar · commit d3f409d88819 · 2026-05-05T09:50:44.000+02:00
RV3032 PMU register should be set from DTS info, but is always being
set to 0 which prevents backup power source configuration.

Restore building PMU reg from DTS.
