soc/broadwell: set EM4/EM5 registers based on cdclk
The EM4/EM5 registers in the mini-HD audio device must be set based on the GPU cdclk value in order for HDMI audio to function properly. Add variables to save the correct values when initializing the GPU, and accessor functions to retrieve them in order to set the registers when initializing the mini-HD audio device.
