cxl: New hcalls to support cxl adapters
The hypervisor calls provide an interface with a coherent platform
facility and function. It matches version 0.16 of the 'PAPR changes'
document.
The following hcalls are supported:
H_ATTACH_CA_PROCESS Attach a process element to a coherent platform
function.
H_DETACH_CA_PROCESS Detach a process element from a coherent
platform function.
H_CONTROL_CA_FUNCTION Allow the partition to manipulate or query
certain coherent platform function behaviors.
H_COLLECT_CA_INT_INFO Collect interrupt info about a coherent.
platform function after an interrupt occurred
H_CONTROL_CA_FAULTS Control the operation of a coherent platform
function after a fault occurs.
H_DOWNLOAD_CA_FACILITY Support for downloading a base adapter image to
the coherent platform facility, and for
validating the entire image after the download.
H_CONTROL_CA_FACILITY Allow the partition to manipulate or query
certain coherent platform facility behaviors.
