programmer: Add bitbanging programmer driver for Linux libgpiod

With this driver, any single board computer, old smartphone, etc. with
a few spare GPIOs can be used for flashrom.

An example invocation looks like this:

flashrom -p linux_gpiod:gpiochip=0,cs=18,sck=19,mosi=13,miso=56

This uses /dev/gpiochip0 with the specified GPIO numbers for the SPI
lines. All arguments are required.

Found GigaDevice flash chip "GD25LQ16" (2048 kB, SPI) on linux_gpiod.
