OBdiag USB test fails.

Bad parsing in obp/pkg/dropins/methods.fth:level2? resulting in random failure depending on garbage in string heap.

• The USB test was failing because the setup_pci_fcodes part of obdiag was not being called for the USB node.
• Setup_pci_fcodes is part of obdiag's "/.init" routine.
• In obp/pkg/dropin/methods.fth, method open-dropin-device performs two opens; one on the diag fcode itself, and a second open on obdiag/.init
• The second open was failing, and thus setup_pci_fcodes was never invoked for this device.
• The second open was failing because the name given to the open was /flashprom:obdiag/pci1083,1103/.init instead of the correct /flashprom:obdiag/.init - thus nothing was found.
• The incorrect name was being generated because the method level2? is supposed to strip the second node in a multi-node name, and wasn't.
• Level2? was failing because it started looking for a "/" one character *after* the name supplied, and by coincidence of the length of the USB node name with the precise positioning of the slashes in a previous string examined, we ended up with a slash right after the "3". The method level2? would detect that slash and exit immediately, failing to split the nodename.

The fix is upgrade OBP to 4.18.6

OBP has been updated to correct method obp/pkg/dropins/methods.fth:level2? to only examine characters *within* the string supplied.

• Updated FIN to remove mention of V880 & V890 and correct OBP revision levels.

None.
