flash/nor/stellaris: add all Tiva C parts IDs

Luckily, TI's website has predictable URLs for the datasheets, so it
was trivial to download all the pdfs corresponding to the currently
available 71 TivaC devices. Then they were processed with pdftotext
and parsed by this script:

BEGIN { capture = -1 }
/^Device Identification 0 \(DID0\)$/ { state = "waitingclass0" }
/^Device Identification 1 \(DID1\)$/ { state = "waitingpartno0" }
/^CLASS$/ { if (state == "waitingclass0") state = "waitingclass"
    else if (state == "waitingclass") capture = 4 }
/^PARTNO$/ { if (state == "waitingpartno0") state = "waitingpartno"
    else if (state == "waitingpartno") capture = 4 }
(FNR == 3) { family = $2 }

{
    if (capture >= 0) {
	if (capture == 0) {
	    if (state == "waitingclass")
		class = $0
	    else if (state == "waitingpartno")
		partno = $0
	}
	capture--
    }
}

END { print "{" class ", " partno ", \"" family "\"}," }
