To prepare for the addition of RK3399 HDMI support, the HDMI driver is
refactored and broken into a chip-specific and a generic part. This
change adds the internal interfaces, makes common/reusable functions
externally visible and splits the RK3288 driver into a separate file.
For the probing of regulators, we reuse the infrastructure created
during the VOP refactoring... i.e. we simply call into the helper
function defined for the VOP.
