A name is pointless if there is only one. Also, the name should be what 
the signal in the block is called which I doubt would be called "ahci". 
A likely name is some form of reset, resetn, etc. which again is 
pointless to name if there is only 1.

If you do have 'reset-names' then that needs to be listed too like 
phy-names.
