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
