Add the required structure definitions for the camera request
manager driver. These changes include IOCTL definitions, op codes,
and payload information. These definitions will allow user space
to make IOCTL calls into the request manager driver.

This adds a header file for use by userspace programs wanting to interact with
the kernel cxl driver. It defines structs and magic numbers required for
userspace to interact with devices in /dev/cxl/afuM.N.
Further documentation on this interface is added in a subsequent patch in
Documentation/powerpc/cxl.txt.
It also adds this new userspace header file to Kbuild so it's exported when
doing "make headers_installs".
