We should remove this after we enable the relocate feature.

We cannot init the CPU fully both than once during a boot. Add a new

Unfortunately this has a dramatic impact on the pre-relocation memory
used on x86 platforms (increasing it by 2KB) since it increases the
overhead for each PCI device from 220 bytes to 412 bytes.
This means that all PCI devices have the controller struct associated
with them. The solution is to move the regions[] member out of the array,
makes its size dynamic, or split UCLASS_PCI into controllers and
non-controllers, as the comment suggests.

Strictly speaking it would be possible for any two of the three to be 'y'

the new logic, since OF_PLATDATA always ensures that no device-tree file
