ocxl: Address kernel doc errors & warnings
This patch addresses warnings and errors from the kernel doc scripts for
the OpenCAPI driver.
It also makes minor tweaks to make the docs more consistent.

ocxl: Provide global MMIO accessors for external drivers
External drivers that communicate via OpenCAPI will need to make
MMIO calls to interact with the devices.

ocxl: move event_fd handling to frontend
Event_fd is only used in the driver frontend, so it does not
need to exist in the backend code. Relocate it to the frontend
and provide an opaque mechanism for consumers instead.

ocxl: Allow external drivers to use OpenCAPI contexts
Most OpenCAPI operations require a valid context, so
exposing these functions to external drivers is necessary.

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.
