On Haikou devkit, it is possible to disable eMMC and SPI-NOR to force booting from SD card or USB via rkdeveloptool by toggling a switch. This switch needs to be overridden in software to be able to access eMMC and SPI-NOR once the device has booted from SD Card. Puma SoM can override this pin via gpio3_d5. Until now, fixed regulator device was abused to model this, but since there's now support for GPIO hogs, let's use it. Since we want to be able to boot the SPL from SD Card but give it the ability to load U-Boot proper from a fallback medium such as eMMC and SPI-NOR, SPL support for GPIO hogs needs to be enabled too. Support for other kinds of regulators are not needed anymore, so let's disable them.
