Subject: [PATCH v2 0/3] Panfrost BO tagging and GEMS debug display

This patch series is a Panfrost port of the already merged patches
previously discussed at [1].

The differences are minimal. However, Panfrost doesn't have Kernel-only BO's, so all the
functionality that dealt with them has been removed.

The under-discussion Mesa MR that would allow one to test these changes can be found at [2].

The way BO flags is printed is also slightly different.

Discussion of previous version in the series can be found at [3]

Changelog:

v2:
 - Introduced u64_to_user_ptr() for casting user pointers
 - Refined documentation for uAPI bo labelling struct fields
 - Moved panfrost device debugfs struct fields into a single debugfs struct
 - Add BO to debugfs GEMs list right before creating its handle to avoid unnecessary initialised field.
