Hello build bot (Jenkins), Edward O'Callaghan, Angel Pons, Daniel Campello, Anastasia Klimchuk, Patrick Rudolph,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/flashrom/+/49643

to look at the new patch set (#6).

Change subject: libflashrom: Return progress state to the library user

libflashrom: Return progress state to the library user

Projects using libflashrom like fwupd expect the user to wait for the operation
to complete. To avoid the user thinking the process has "hung" or "got stuck"
report back the progress complete of the erase, write and read operations.

Include a test for the dummy spi25 device.
