Updated firmware version sets BIT(4) in custom type flags to mark a divider as fractional divider since BIT(13) is defined as CLK_DUTY_CYCLE_PARENT in the common clk framework flags. To support both old and new firmware version, consider BIT(13) from clkflag and BIT(4) from type_flag to check if divider is fractional or not. To maintain compatibility BIT(13) of clkflag in firmware will not be used in future for any purpose and will be marked as unused.
