drm/ast: Store DRAM clock table in struct ast_device 



Init the new field dclk_table in struct ast_device to the per-gen
table of DRAM clock parameters. Use the field during modesetting.

The table is static, so a setup is only required once. Removes the
call to IS_AST_GEN() from the atomic commit's code path.
