DB8500 has irqs from two cores ORed into one. Implement a
workaround to handle this by bouncing the interrupt by setting
the affinity to the other core when the interrupt appears to
be spurious on the current core.

Change the Ux500 devices to be dynamically allocated and added by
calling functions instead of referencing structures, thereby allowing
5500 and other derivatives' support to be added without having to
duplicate structures, use fixup functions, or use compile-time macros.

This patch adds support for checking if the digital baseband (DB)
System-on-Chip (aka "cpu) ASIC hardware version is 1.0, 1.1 or
2.0. We print the result in the bootlog, the functions are then
used for runtime decisions based on hardware version.
