Introduce the `i2c_open_from_programmer_params` function to avoid having
to duplicate parameter parsing code on all I2C programmers. This also
allows having the same programmer parameters on all I2C programmers.

Use tabs to indent code and drop an unnecessary newline.

Some callers may find it easier to provide the path to an I2C device
at which to communicate with the device, rather than specify the bus
number- doing so might involve trying to parse a path to extract the
number only for flashrom to do the reverse, which is error-prone and
unnecessary.
This change adds support for a `devpath` option, continuing to
allow `bus` and requiring only one of them be specified.
TEST=Verified --flash-size outputs correct values with both
devpath=/dev/i2c-7 and bus=7, as well as noting that one is
required if neither is specified and only one may be specified
if both are given.

Given that the buffer size is known in advance, using malloc() is not
necessary. To avoid open-coding buffer sizes, add some trailing null
characters to `I2C_DEV_PREFIX`, as placeholders for bus number digits.
Finally, replace the now-unnecessary `goto` statements with `return`.

AFAIK, this shouldn't break anything, as glibc just includes fcntl.h
from sys/fcntl.h.

See https://www.kernel.org/doc/Documentation/i2c/ for details.
This creates common interface for I2C access functions, and adds
implementation for linux I2C functions.
