clk: renesas: rzv2h: Add instance field to struct pll 



Add a two-bit "instance" member to struct pll and extend the PLL_PACK()
macro to accept an instance parameter.  Initialize all existing PLL
definitions with instance 0 to preserve legacy behavior. This change
enables support for SoCs with multiple PLL instances (for example,
RZ/G3E we have two PLL DSIs).
