ASPEED device tree updates for 4.18

Browse source 
New hardware support added:
 
   USB controllers for AST2400 and AST2500 which have drivers
   merged in 4.18.
 
   Hardware random number generator which we made enhancements to many
   releases ago, but never added the device tree parts.
 
   Misc changes to support watchdog and gpio-keys features used by
   OpenBMC systems.
 
 New machines:
 
  Intel S2600WF, an Intel platform family with an ASPEED AST2500 BMC.
 
  Inventec Lanyang, a Power 9 platform with AST2500.
 
  Portwell Neptune, a x86 server development kit with an AST2500.
