The PTC[RXWM] sets the watermark value for Rx FIFO. The default value 0x20 might be insufficient for some hard drives. If the watermark value is too small, a single-cycle overflow may occur and is reported as a CRC or internal error in the PxSERR register. Updated the value to 0x29 according to the validation test. All LS platforms are affected.
