drm/xe/debugfs: Make residencies definitions const

Browse Source 
No need to keep them non-const. Also fix declaration of .name
member, as it points to the const string. This translates to:

  add/remove: 1/0 grow/shrink: 0/2 up/down: 80/-248 (-168)
  Function                                     old     new   delta
  residencies                                    -      80     +80
  dgfx_pcie_link_residencies_show              365     263    -102
  dgfx_pkg_residencies_show                    454     308    -146
  Total: Before=2821548, After=2821380, chg -0.01%
