TQM866M: fix SDRAM refresh
At 133 MHz the current SDRAM refresh rate is too fast (measured 4 * 1.17 us). CFG_MAMR_PTA changes from 39 to 97. This result in a refresh rate of 4 * 7.8 us at the default clock 50 MHz. At 133 MHz the value will be then 4 * 2.9 us. This is a compromise until a new method is found to adjust the refresh rate. Signed-off-by: Martin Krause <martin.krause@tqs.de>
