Subject: [PATCH 7/7] drm/msm/dpu: Rename `ctx` parameter to `intf` to match other functions

All other functions in dpu_hw_intf name the "self" parameter `intf`,
except dpu_hw_intf_setup_timing_engine() and the recently added
dpu_hw_intf_program_intf_cmd_cfg(). Clean that up for consistency.

I really have mixed feelings towards such patches. On one hand it
improves readability, on the other hand, it's just a name, it has no
specific value.

Still:
