[PATCH 04/11] power: pmic: Make the uclass optional in SPL

[Samuel Holland]

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.
