Andre Przywara 67412e4d7a feat(allwinner): allow to skip PMIC regulator setup For somewhat historical reasons we are doing some initial PMIC regulator setup in BL31, as U-Boot does not (yet) have a PMIC driver. This worked fine so far, but there is at least one board (OrangePi 3) that gets upset, because the Ethernet PHY needs some coordinated bringup of two regulators. To avoid custom hacks, let's introduce a build option to keep doing the regulator setup in TF-A. Defining SUNXI_SETUP_REGULATORS to 0 will break support for some devices on some boards in U-Boot (Ethernet and HDMI), but will allow to bring up the OrangePi 3 in Linux correctly. We keep the default at 1 to not change the behaviour for all other boards. After U-Boot gained proper PMIC support at some point in the future, we will probably change the default to 0, to get rid of the less optimal PMIC code in TF-A.
