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.
