According to the M31 EUSB2 PHY hardware documentation, this bit is intended only for test/debug scenarios and does not control mission mode operation. Keeping PLL_EN asserted causes the PHY to draw additional current during USB bus suspend. Clearing this bit results in lower suspend power consumption without affecting normal operation. Update the driver to leave PLL_EN cleared as recommended by the hardware documentation.
