Add VIA VT6421A LPC programmer driver.

Due to the mysterious address handling of this chip the user can specify
a base address with the offset parameter, e.g.:
flashrom -p atavia:offset=0xFFF00000

Thanks to Idwer Vollering for his iterative testing of this code, as well as to
Martijn Bastiaan who did the last tests before merging.
