Probably most of NXP LPC32xx boards have 13MHz main oscillator and therefore for HCLK PLL and ARM core clock rate default hardware setting is 16 * 13MHz = 208MHz, however a user may vary HCLK PLL/ARM core rate from 156MHz to about 266MHz for 13MHz clock source. The change explicitly defines HCLK PLL output rate to default 208MHz to overwrite any settings done by a bootloader, if needed it can be redefined in a board DTS file.
