flashrom: Probe for up to 3 flash chips.
Currently there is an ongoing technology migration from LPC/FWH to SPI chips.
For this reason some boards have multiple chips of different technologies
onboard. This patch makes flashrom probe for up to 3 chips and if more than
one chip is found flashrom exits, asking the user to specify -c.
[root@localhost src]# ./flashrom
...
Multiple flash chips were detected: SST49LF008A M25P16@ICH9
Please specify which chip to use with the -c <chipname> option.
