The xa_alloc*() functions family takes a struct xa_limit to describe the range of IDs the caller wants to allocate. We were using a single mask to qualify a maximum ID only.
This commit changes that to use the same struct xa_limit. The logic did not change, except it now supports a minimum ID as well. The definition of XA_LIMIT() macro is adapted, as well as the definitions of xa_limit_* (only xa_limit_32b existed, the other two are added with this commit).
The DRM generic code started to use this struct xa_limit in Linux 6.12.
This is part of the update of DRM drivers to Linux 6.12.
