Create patch_hdmi.c to hold common code from intelhdmi and nvhdmi.
For now the patch_hdmi.c file is simply included by patch_intelhdmi.c and patch_nvhdmi.c, and does not represent a real codec.
There are no behavior changes to intelhdmi. However nvhdmi made several changes when copying code out of intelhdmi, which are all reverted in this patch. Wei Ni confirmed that the reverted code actually works fine.
