radeon: Narrow diff a little bit.

radeon: Reduce #ifdef __NetBSD__ around condvars.

drm: Sprinkle BUS_DMA_COHERENT/NOCACHE and bus_dmamap_sync.

Algorithm:

- For dummy pages, use NOCACHE and PREREAD|PREWRITE.
- In #ifdef __NetBSD__ #else dma_alloc_coherent, use BUS_DMA_COHERENT.
- For (GPU) page tables we program, use PREWRITE.

Merge linux-drm-v5-6-rc3

Reduce diffs by side-loading some header files like Linux.

From riastradh

Stub out console_lock/unlock and drm_fb_helper_set_suspend.

Reduce some more diffs.

Use a header file hack to cope with Linux/NetBSD namespace clashes.

Currently serves for:

ALIGN
mutex_init
mutex_destroy

Zero the dummy page

branches: 1.6.6;
Ifdef out radeon vga in error branch.

Assume we're not a VM guest in radeon for now.

Not sure exactly what the consequences of this are but we'll cross
that bridge when we come to it.

branches: 1.3.2; 1.3.6; 1.3.30; 1.3.32;
In radeon_device_init, use ddev->dev, not &pdev->dev, for rdev->dev.

ddev->dev is the actual device_t, and we need it for firmware load.
&pdev->dev is a dummy structure that serves no purpose except some
kludge in our Linux PCI compatibility crap. In Linux the two should
be the same, so no need to #ifdef __NetBSD__ this.

First whack at radeon driver.

No hardware to test yet, but it builds.
