* Clean up stdout-path to include only &serial0
* Rename uart to serial
* Remove aliase entry since not needed

Please use "snps,dwc-ahci" as the compatible string for a designware
ahci controller, not "snps,spear-ahci", which refers to the implementation
of that in the ST microelectronics SPEAr consumer SoC.
It would be good to also add a string that is specific for your SoC if
we ever need to identify it directly.
