Convert existing CLK_FIXED_FACTOR definitions to either the _HW or _FW_NAME variant based on whether the parent clock is internal or external to the CCU. A forward declaration for struct clk_fixed_factor pll_periph0_4x_clk is added as the definitions of the fixed factor clocks appear much later in the file. The position of fixed factor clock definitions will be moved for all drivers at a later time, before the conversion of all other clock types.
