cxl/core/regs: Add @dev to cxl_register_map
The corresponding device of a register mapping is used for devm
operations and logging. For operations with struct cxl_register_map
the device needs to be kept track separately. To simpify the involved
function interfaces, add @dev to cxl_register_map.
While at it also reorder function arguments of cxl_map_device_regs()
and cxl_map_component_regs() to have the object @cxl_register_map
first.
As a result a bunch of functions are available to be used with a
@cxl_register_map object.
This patch is in preparation of reworking the component register setup
code.
