cli_classic: Use flashrom_init() from API

flashrom_init() already does delay calibration and self-checking
via the canonical libflashrom API. Port the cli implementation
to go via the libflashrom API entry-point natively.

Tested: ```sudo ./flashrom -p internal --flash-size
<snip>
Found Programmer flash chip "Opaque flash chip" (16384 kB, Programmer-specific) mapped at physical address 0x0000000000000000.
