Our platforms(such as LS1021A, LS1012A, LS1043A, LS1046A, LS1028A) with
below registers(CHCFG0 - CHCFG15) of eDMA as follows:
*-----------------------------------------------------------*

|--------------|--------------------|-----------------------|
| 0x0 | CHCFG0 | CHCFG3 |
|--------------|--------------------|-----------------------|
| 0x1 | CHCFG1 | CHCFG2 |
|--------------|--------------------|-----------------------|
| 0x2 | CHCFG2 | CHCFG1 |
|--------------|--------------------|-----------------------|
| 0x3 | CHCFG3 | CHCFG0 |
|--------------|--------------------|-----------------------|
| ... | ...... | ...... |
|--------------|--------------------|-----------------------|
| 0xC | CHCFG12 | CHCFG15 |
|--------------|--------------------|-----------------------|
| 0xD | CHCFG13 | CHCFG14 |
|--------------|--------------------|-----------------------|
| 0xE | CHCFG14 | CHCFG13 |
