This patch series brings some fixes to the Qualcomm DPU driver, aim is
to get it prepared for "legacy" SoCs (like MSM8998, SDM630/660) and to
finally get command-mode displays working on this driver.

The series was tested against MSM8998 (the commit that introduces it to
the hw-catalog is not included in this series, as it needs to be cleaned
up a little more) and specifically on:
- Sony Xperia XZ Premium (MSM8998), 4K dual-dsi LCD display, command-mode
- F(x)Tec Pro1 (MSM8998), single-dsi OLED display, video-mode

... And it obviously worked just perfect!
