[PATCH v3 0/9] Some Panfrost fixes and improvements

["Adrián Larumbe" <adrian.larumbe@collabora.com>]

This is v3 of https://lore.kernel.org/dri-devel/20241128211223.1805830-1-adrian.larumbe@collabora.com/

This patch series is a collection of minor fixes and improvements I came up
with while working on driver related stuff.

Changelog:
v3:
 - Minor convenience fixes to patches 3 and 4 in the series
 - Move unmapping of maped range of BO to the function's error path
 in case of BO mapping failure, also for putting BO's pages
 - Split patch 6/8 into two: one makes sure the Job IRQ enablement mask
 isn't recalculated at every device reset and uses the same expression
 everywhere in the driver, and another one that breaks the enablement
 function into two stages.
v2:
 - Removed commit that provided an explicit fence cleanup function
 - Added commit for removing unused Panfrost device structure member
 - Refactored how optional job interrupt reenabling during reset is handled
 - Make the way errors and successful return values are delivered from inside
  panfrost_mmu_as_get more according to standard.
 - Simplify unmapping of already mapped area when mapping the pages of a BO
 - Fixing management of runtime-PM reference counts when failing HW job submission.
