[ Upstream commit f4c7fa39415da6db1fa0bc26162ac23a0fbae8bb ]
The VDDA LDO1 PMIC output supplies the analog VDDA input of the
STM32MP1 on DHCOM, keep it always on, otherwise there could be
leakage through the SoC.
Fixes: 34e0c7847dcf ("ARM: dts: stm32: Add DH Electronics DHCOM STM32MP1 SoM
and PDK2 board")
