For determining the PMIC type and the bus its connected to, we use the
DTB that is appended to the U-Boot binary, by looking for it in DRAM.
And while we bail out correctly if we don't find it there, we later try
to use the DTB pointer - without checking.
Add a check in sunxi_pmic_setup(), to only proceed if we have found a
DTB before, and exit early otherwise.
This fixes more experimental setups, where TF-A is run without U-Boot.
