Hello build bot (Jenkins), Daniel Campello, Angel Pons, Anastasia Klimchuk,

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

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

Change subject: flashrom: Convert do_read() into a libflashrom user

flashrom: Convert do_read() into a libflashrom user

Aspire towards a goal of making cli_classic more of just
a user of libflashrom than having quasi-parallel paths in
flashrom.c

This converts the do_read() provider wrapper into a pure
libflashrom user.

BUG=b:208132085
TEST=`$ sudo ./flashrom -p internal -r /tmp/bios.bin`
