I think I missed ls1012a and ls1021a.  Commit message is wrong. This is
for legancy platorm. 

Basic try to eliminate the CHECK_DTBS warning. ls1012a use

"fsl,ls1012a-ahci", "fsl,ls1043a-ahci". There are two methods, 
1. change binding doc to allow "fsl,ls1012a-ahci", "fsl,ls1043a-ahci"
2. remove "fsl,ls1012a-ahci".

which way do you perfer?
