[Toybox] [PATCH] lspci -i (was Re: [CLEANUP] lspci first pass)

[Isaac Dunham]

lspci text output: add -i, allow -n when disabled

-i is how standard lspci handles changing the PCI ID database.
lspci -n should be a no-op when text is disabled.
--
I don't know the best way to document that -i should normally point to 
/path/to/pci.ids ... please adjust the help appropriately.

Surprisingly enough, "emkn"USE_LSPCI_TEXT("@i:") works without any 
mucking around.


Thanks,
Isaac Dunham
