[PATCH v2 1/7] drm/ast: Replace AST_VIDMEM_SIZE_ with Linux SZ_ constants

[Thomas Zimmermann <tzimmermann@xxxxxxx>]

Ast's AST_VIDMEM_SIZE_ constants enumerate supported video-memory
sizes from 8 MiB to 128 MiB. Replace them with Linux' SZ_ constants
of the same value. When expanded, the literal values remain the same.

The size constant for 128 MiB is unused and the default size is not
necessary. Remove both of them.
