drop drmP.h usage? [Was: [pull] amdgpu, amdkfd drm-next-5.3]

Hi Alex et all.

• Various cleanups

Any chance to persuade one of you guys to sweep through the amd / raedeon tree and drop use of the deprecated header drmP.h?

Status at the moment (drm-misc-next): $git grep drmP | cut -d '/' -f 1 | uniq -c | sort -n | tail -n 10 11 meson 12 mediatek 13 vmwgfx 15 rockchip 16 sti 18 sun4i 24 exynos 27 nouveau 103 radeon 110 amd

nouveau is already taken care of, the cleanup is in their tree. amd and radeon are the two "worst" drivers in this respect at the moment.

Thanks, Sam
