[PATCH 01/14] drm/ast: Fix DRAM init on AST2200

[Thomas Zimmermann]

Fix the test for the AST2200 in the DRAM initialization. The value
in ast->chip has to be compared against an enum constant instead of
a numerical value.

This bug got introduced when the driver was first imported into the
kernel.
