[PATCH] arm64: dts: st: mark main supplies always-on on stm32mp257f-dk

[Mateusz Nowicki]

The vddcore, v1v8 and v3v3 regulators have no consumer in Linux, so
the regulator core disables them 30 seconds after boot. They supply
the SoC digital logic, the SoC 1.8 V analog domain and the 3.3 V board
peripherals, and must stay on while Linux runs.

Mark them always-on.
