struct intel_dpll_hw_state has a spot for all possible PLL registers across all platforms (well, apart from cx0/snps). This makes it rather confusing when trying to figure out which members belong to which platform(s). Split the struct up into five different platform specific sub-structures. For now this will actually increase the size a little bit as we have to duplicate a few members from skl to icl, but that will be remedied soon when we turn the thing into a union.
