bios: support for tool: flashcp
flashcp as an alternative to flashrom which is already present in some
images.
Tested: On Tyan S8030
Set
```
"Tool": "flashcp"
```
in the EM json config.
Using the images from [1], update to v4.01 and v4.03, dump the
flash contents and compare md5sum output for both the image and flash
dumps after each update.
```
