ocxl: Don't return trigger page when allocating an interrupt
Existing users of ocxl_link_irq_alloc() have been converted to obtain the trigger page of an interrupt through xive directly, we therefore have no need to return the trigger page when allocating an interrupt.
It also allows ocxl to use the xive native interface to allocate interrupts, instead of its custom service.

ocxl: Update for AFU descriptor template version 1.1
The OpenCAPI discovery and configuration specification has been updated and introduces version 1.1 of the AFU descriptor template, with new fields to better define the memory layout of an OpenCAPI adapter.
The ocxl driver doesn't do much yet to support LPC memory but as we start seeing (non-LPC) AFU images using the new template, this patch updates the config space parsing code to avoid spitting a warning.

ocxl: Create a clear delineation between ocxl backend & frontend
The OCXL driver contains both frontend code for interacting with userspace, as well as backend code for interacting with the hardware.
This patch separates the backend code from the frontend so that it can be used by other device drivers that communicate via OpenCAPI.
Relocate dev, cdev & sysfs files to the frontend code to allow external drivers to maintain their own devices.
Reference counting on the device in the backend is replaced with kref counting.
Move file & sysfs layer initialisation from core.c (backend) to pci.c (frontend).

ocxl: Add a kernel API for other opencapi drivers
Some of the functions done by the generic driver should also be needed by other opencapi drivers: attaching a context to an adapter, translation fault handling, AFU interrupt allocation...
So to avoid code duplication, the driver provides a kernel API that other drivers can use, similar to calling a in-kernel library.
It is still a bit theoretical, for lack of real hardware, and will likely need adjustements down the road. But we used the cxlflash driver as a guinea pig.

ocxl: Update for AFU descriptor template version 1.1 The OpenCAPI discovery and configuration specification has been updated and introduces version 1.1 of the AFU descriptor template, with new fields to better define the memory layout of an OpenCAPI adapter. The ocxl driver doesn't do much yet to support LPC memory but as we start seeing (non-LPC) AFU images using the new template, this patch updates the config space parsing code to avoid spitting a warning.

ocxl: Create a clear delineation between ocxl backend & frontend The OCXL driver contains both frontend code for interacting with userspace, as well as backend code for interacting with the hardware. This patch separates the backend code from the frontend so that it can be used by other device drivers that communicate via OpenCAPI. Relocate dev, cdev & sysfs files to the frontend code to allow external drivers to maintain their own devices. Reference counting on the device in the backend is replaced with kref counting. Move file & sysfs layer initialisation from core.c (backend) to pci.c (frontend). Create an ocxl_function oriented interface for initing devices & enumerating AFUs.

ocxl: Add a kernel API for other opencapi drivers Some of the functions done by the generic driver should also be needed by other opencapi drivers: attaching a context to an adapter, translation fault handling, AFU interrupt allocation... So to avoid code duplication, the driver provides a kernel API that other drivers can use, similar to calling a in-kernel library. It is still a bit theoretical, for lack of real hardware, and will likely need adjustements down the road. But we used the cxlflash driver as a guinea pig.
