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.
