Subject: [PATCH] clk: sunxi-ng: sun6i: Fix enable bit offset for hdmi-ddc module clock

The enable bit offset for the hdmi-ddc module clock is wrong. It is
pointing to the main hdmi module clock enable bit.

Hi Bob,

Can you try this patch and see if it fixes your HDMI issue?
With the kernel running without "clk_ignore_unused" that is.
