Factor out common mptable code to mptable_init().

Factor out common mptable code to mptable_init().

 - Drop sig[], oem[], and productid[] fields in all mptable.c files, no
   longer needed. The sig[] is always the same ("PCMP"), the oem[] is
   currently also always the same ("COREBOOT"), and productid is being
   passed into mptable_init() directly as string now.

 - LAPIC_ADDR is passed in as parameter, too. While at the moment it's
   always the same value that is passed in, the LAPIC base address could
   also be relocated theoretically, so keep it as parameter for now.

 - Fix a few productid entries, they were (partially) incorrect:

   - DK8S2 (was "DK8X", copypaste)
   - 939A785GMH (was "MAHOGANY", copypaste)
   - X6DHE-G (was "X6DHE", incomplete board name)
   - H8DME-2 (was "H8DMR", copypaste)
   - H8QME-2+ (was "H8QME", incomplete board name)
   - X6DHE-G2 (was "X6DHE", incomplete board name)
   - X6DHR-iG2 (was "X6DHR-iG", incomplete board name)
   - GA-M57SLI-S4 (was "M57SLI", incomplete board name)
   - KINO-780AM2 (was "KINO", incomplete board name)
   - DL145 G1 (was "DL145G1", small fix as per vendor website)
   - DL145 G3 (was "TREX", wrong board name)
   - DL165 G6 (was "HP DL165 G6", drop vendor)
   - S2912 (was "S2895", copypaste)
   - VT8454c (was "VIA VT8454C", drop vendor, lower-case "c")
   - EPIA-N (was "P4DPE", copypaste)
   - pc2500e (was "PC2500", incorrect name)
   - S1850 (was "S2850", copy-paste)
   - MS-7135 (was "MS7135")
   - MS-9282 (was "MS9282")
   - MS-9185 (was "MS9185")
   - MS-9652 (was "K9ND MS-9652")
   - Ultra 40 (was "ultra40")
   - E326 (was "E325", copypaste)
   - M4A785-M (was "TILAPIA", copypaste)
   - P2B-D (was "ASUS P2B-D", drop vendor)
   - P2B-DS (was "ASUS P2B-DS", drop vendor)

 - Adapt the mptable utility to use mptable_init() too.

Abuild-tested.
