pmic_init() and nor_early_init() panic when the board device tree describes no PMIC or no SPI controller to the SPL. The OrangePi R2S boots from eMMC with its rails already up, and boards that boot from eMMC or microSD need no SPI NOR, so the SPL stops before it can load U-Boot. Log the missing device and carry on instead. If the SPL then has to boot from SPI without a controller, spl_spi_load_image() reports it.
