[PATCH] cxl: Include range.h in cxl.h

[Nathan Chancellor <nathan@kernel.org>]

After commit aefeb286b960 ("libnvdimm: Don't use "proxy" headers"),
range.h may not be implicitly included, resulting in a build error:

  In file included from drivers/cxl/core/features.c:8:
  drivers/cxl/cxl.h:365:22: error: field 'hpa_range' has incomplete type
    365 |         struct range hpa_range;
        |                      ^~~~~~~~~

  drivers/cxl/cxl.h:570:22: error: field 'hpa_range' has incomplete type
    570 |         struct range hpa_range;

  drivers/cxl/cxl.h:803:22: error: array type has incomplete element type 'struct range'
    803 |         struct range dvsec_range[2];
        |                      ^~~~~~~~~~~

Include range.h in cxl.h explicitly to clear up the errors.
