This series moves the definition and the management of scheduled process area
(SPA) and of the templates (Transaction Layer) for an ocxl card, using the
OCAPI interface. The code is now located in the specific arch powerpc platform.
These patches will help for a futur implementation of the ocxl driver in QEMU.

The Open Coherently Attached Processor Interface (OCAPI) is used to
allow an Attached Functional Unit (AFU) to connect to the Processor
Chip's system bus in a high speed and cache coherent manner.

It builds on top of the existing ocxl driver.

It has been tested in a bare-metal environment using the memcpy and
the AFP AFUs.
