Add the reg_sequence to initialize the HDMI PLL with the settings for a video mode that doesn't require PLL internal clock doubling. These settings are taken from the 3.10 vendor kernel's driver for the 2970MHz PLL setting used for the 1080P video mode. This puts the PLL into a defined state and the Linux kernel can take over. While not all bits for this PLL are implemented using these "defaults" and then applying M, N and FRAC seems to work fine.
