[PATCH v4 2/3] Documentation: dt: binding: fsl: Add 'little-endian' and update Chassis define

[Ran Wang]

By default, QorIQ SoC's RCPM register block is Big Endian. But
there are some exceptions, such as LS1088A and LS2088A, are Little
Endian. So add this optional property to help identify them.

Actually LS2021A and other Layerscapes won't totally follow Chassis
2.1, so separate them from powerpc SoC.

Change in v4:
- Adjust indectation of 'ls1021a, ls1012a, ls1043a, ls1046a'.

Change in v3:
- None.

Change in v2:
- None.
