Generify support for ITE IT8705 Super I/O

Autodetect the ITE IT8705 Super I/O and enable flash writes if it
performs LPC->Parallel translation. Remove board enables which triggered
the IT8705 write enable manually. Change the IT87 SPI special case to
cover IT87 LPC->SPI and LPC->Parallel translation.

Corresponding to flashrom svn r1073.
