drm: Mark AGP implementation and ioctls as legacy

Only UMs drivers use DRM's core AGP code and ioctls. Mark the icotls
as legacy. Add the _legacy_ infix to all AGP functions. Move the
declarations to the public and internal legacy header files. The agp
field in struct drm_device is now located in the structure's legacy
section. Adapt drivers to the changes.

AGP code now depends on CONFIG_DRM_LEGACY.

This commit fixes DRM failures on Xen PV systems that were introduced in

fd5fd480 drm/amdgpu: only enable swiotlb alloc when need v2

The introduction of ->need_swiotlb to the ttm_dma_populate() conditionals
in the radeon and amdgpu device drivers causes Gnome to immediately crash
on Xen PV systems, returning the user to the login screen. The following
kernel errors get logged:

treewide: Use array_size() in vmalloc()

The vmalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

vmalloc(a * b)

with:
vmalloc(array_size(a, b))

as well as handling cases of:

vmalloc(a * b * c)

with:

vmalloc(array3_size(a, b, c))

This does, however, attempt to ignore constant size factors like:

vmalloc(4 * 1024)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:
