Some platforms still cannot use the driver model in SPL due to SRAM space limitations. However, they need to use DM_PMIC in U-Boot proper. Add a new symbol so that DM_PMIC can be disabled in SPL, while keeping it available elsewhere. Also update the SPL-specific symbols to depend on this new option.
