flashrom: Drop read_flash_to_file() usage

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 remaining read_flash_to_file() usage to the
do_read() provider wrapper around libflashrom.

BUG=b:208132085
TEST=`
sudo ./flashrom -p ft2232_spi:type=232H,divisor=1000 -f -r out -c W25X05
Flashrom output:

No EEPROM/flash device found.
Force read (-f -r -c) requested, pretending the chip is there:
Assuming Winbond flash chip "W25X05" (64 kB, SPI) on ft2232_spi.
Please note that forced reads most likely contain garbage.
Block protection could not be disabled!
Reading flash... done.
