allwinner: Build PMIC bus drivers only in BL31
These are used by the PMIC setup code, which runs during BL31
initialization, and the PSCI shutdown code, also a part of BL31.
They can't be needed before BL31, or it wouldn't be possible to boot.
Allwinner platforms don't generally build anything but BL31 anyway, but
this change improves clarity and consistency with allwinner-common.mk.
