cxl/region: Add dev_dbg() detail on failure to allocate HPA space
When the region driver fails while allocating HPA space for a
new region it can be because the parent resource, the CXL Window,
has no more available space.
In that case, the debug user sees this message:
cxl_core:alloc_hpa:555: cxl region2: failed to allocate HPA: -34
Expand the message like this:
cxl_core:alloc_hpa:555: cxl region8: HPA allocation error (-34) for size:0x20000000 in CXL Window 0 [mem 0xf010000000-0xf04fffffff flags 0x200]
Now the debug user can examine /proc/iomem and consider actions
like removing other allocations in that space or reducing the
size of their region request.
