Subject: [PATCH 1/3] OMAP: DSS2: VRAM: Fix early_param for vram
In commit 2b0d8c251b8876d530a6bf671eb5425838fa698a the __early_param is
replaced with the generic early_param. This patch fixes the parameter passing
for the vram.

Subject: [PATCH 2/3] OMAP: DSS2: initialize dss clk sources properly
Clk sources were not initialized, leading to kernel crash, or possibly to
strange behaviour if DSI was compiled in.
