Fix PAD_CTL_SPEED_LOW pad property macro definition.
PAT_CTL_SPEED_LOW occupies the 6th and 7th bit.
To mx6sx:
0 0 | 50MHZ — Low(50 MHz)
0 1 | 100MHZ — Medium (100 MHz)
1 0 | 100MHZ — Medium (100 MHz)
1 1 | 200MHZ — Maximum (200 MHz)

To Other mx6 socs:
0 0 | RESERVED0 — Reserved
0 1 | 50MHZ — Low (50 MHz)
1 0 | 100MHZ — Medium (100 MHz)
1 1 | 200MHZ — Maximum (200 MHz)
