Ah! Clear. Maybe I was looking at a tree without the patches and got confused.
The patches clearly introduce the "pwm-backlight" for lpss.

Did you see that my kernel log of April shows:

[    2.658013] pwm-byt-plat 80860F09:00: PWM device probed: pwm_num=0,
mmio_base=ffffc90001a46000 clk_khz=25000
[    2.658223] pwm-byt-plat 80860F09:01: PWM device probed: pwm_num=1,
mmio_base=ffffc90001a48000 clk_khz=25000

and only at 15s i915 reports failure to own?

[   15.203281] [drm:pwm_setup_backlight [i915]] *ERROR* Failed to own the pwm
chip: pwm_lpss

Doesn't this mean that the order is already correct?

(I will try the patches here provided though)
