The dynamic tables framework utilizes the configuration manager
protocol to get the platform specific information required for
building the firmware tables.

The configuration manager is a platform specific component that
collates the platform hardware information and builds an abstract
platform configuration repository. The configuration manager also
implements the configuration manager protocol which returns the
hardware information requested by the table generators.

This patch implements the configuration manager support for the
Juno platform.

+  There are two ways that _PRT can be used.
+
+  In the first model, a PCI Link device is used to provide additional
+  configuration information such as whether the interrupt is Level or
+  Edge triggered, it is active High or Low, Shared or Exclusive, etc.
+
+  In the second model, the PCI interrupts are hardwired to specific
+  interrupt inputs on the interrupt controller and are not
+  configurable. In this case, the Source field in _PRT does not
+  reference a device, but instead contains the value zero, and the
+  Source Index field contains the global system interrupt to which the
+  PCI interrupt is hardwired.
+
+  We use the first model with link indirection to set the correct
+  interrupt type as PCI defaults (Level Triggered, Active Low) are not
+  compatible with GICv2.
