devicetree: Rename unused parameter to passthru
The actual use of the parameter max is to keep track of PCI bus number while recursively scanning PCI bridges or PCI-e rootports. Neither CPU, SMBus, LPC or other static buses are involved in this enumeration, but the way bridge operations were originally designed forced to pass this argument thru unrelated functions. Follow-up removes these once the function prototype gets fixed.
