The Innosilicon HDMI PHY IP is used by several SoCs. They differ in where the PHY register block sits in the register space and in which pixel clocks they support, but the pre-PLL programming sequence and the layout of its registers are the same. Add a small library holding that shared part: the pre-PLL configuration table format, a lookup, clk_ops determine_rate and recalc_rate helpers, and the pre-PLL register programming. Callers pass a regmap, a register offset for the PHY block, and their own pixel clock table. No driver uses it yet; the users are converted separately.
