a40932a324 hw: refactor irq controllers
* name irq controller memory mapped I/O regions consistently
  in board descriptions
* move irq controller and timer memory mapped I/O region descriptions
  from cpu class to board class
* eliminate artificial distinction between flavors of ARM's GIC
* factor cpu local initialization out of ARM's GIC interface description,
  which is needed if the GIC is initialized differently e.g. for TrustZone

3a40c27c26 hw_vea9x4: quickfix slow RAM access
Setting the ACTLR.SMP bit also without SMP support fastens RAM access
significantly. A proper solution would implement SMP support which must enable
the bit anyway.

9a4a0448be hw vea9x4: remove trustzone support
When building Genode for VEA9X4 as micro-hypervisor protected by the ARM
TrustZone hardware we ran into limitations regarding our basic daily
testing routines. The most significant is that, when speaking about RAM
partitioning, the only available options are to configure the whole SRAM
to be secure and the whole DDR-RAM to be non-secure or vice versa. The
SRAM however provides only 32 MB which isn't enough for both a
representative non-secure guest OS or a secure Genode that is still
capable of passing our basic tests. This initiated our decision to
remove the VEA9X4 TrustZone-support.

6cb9559feb hw: core as library
The build config for core is now provided through libraries to enable
implicit config composition through specifiers and thereby avoid
consideration of inappropriate targets.
