From: Biju Das <[email protected]> [ Upstream commit 6549ef9cc236cd09d42ae521e459817ae6b5c5fa ] Replace the PLL146_CONF() macro and its associated CPG_SAMPLL_CLK{1,2}(n) helpers with a single CPG_SAM_PLL_CONF(stby) macro that takes the PLL standby register offset directly. This removes the implicit coupling between PLL index n and register layout and eliminates the now-redundant GET_REG_SAMPLL_CLK2() macro. The RZ/V2M PLL4 definition is also updated to use the new macro with its explicit standby offset (0x100), removing the local PLL4_CONF define. No functional changes.
