1748c5c13e ARM: dts: stm32: Move DHCOR BUCK3 VDD 2V9 adjustment to 1V8 DTSI
The Buck3 on DHCOR is used to supply IO voltage. It can output either 3V3
in the default DHCOR configuration, or 2V9 in case of AV96 DHCOR variant
which has extra Empirion DCDC converter in front of the 1V8 IO supply, or
outright 1V8 in case of 1V8 IO DHCOR without the Empirion DCDC converter.

The 2V9 mode in case of AV96 DHCOR variant is used to reduce unnecessarily
high input voltage to the Empirion DCDC converter, so move it into matching
DTSI to stop confusing users.

7e76f82acd ARM: dts: stm32: Split Avenger96 into DHCOR SoM and Avenger96 board
The Avenger96 is in fact an assembly of DH Electronics DHCOR SoM on top
of an Avenger96 reference board. The DHCOR SoM can be populated with any
STM32MP15xx. Split the DTs to reflect this such that the common SoM and
Avenger96 parts are now in stm32mp15xx-dhcor-*dtsi and a specific example
implementation of STM32MP157A SoM and Avenger96 board is separated into
stm32mp157a-dhcor-*dts* . The stm32mp157a-avenger96.dts is retained for
the sake of backward naming compatibility.
