[Linux-stm32] [PATCH 09/22] ARM: dts: stm32: Repair PMIC configuration on AV96

[Marek Vasut]

The core and vdd PMIC buck regulators were misconfigured, which caused
instability of the board and malfunction of high-speed interfaces, like
the RGMII. Configure the PMIC correctly to repair these problems.
