[coreboot] Dell latitude c610

[CybFr]

Hi,

I'd like to re-open a tread from Michal Janke about supporting Dell latitude 
C610 and its SMSC LPC47N252 SuperIO.

- I've found the closest chip from SMSC was FDC37N972, supported by 
superiotool so I added corresponding entries in smsc.c.

- for  FDC, UARTS, KBD, RTC, everything seems quite common so I added it in 
/superio/smsc/smsssuperio/superio.c.
(the big difference betweenn supported smsc chips an LPC47N252 is the 
EC-8051 core... )

What could be the next step ?

Thanks for advices
