arm/vexpress: Add proper display connector emulation
This adds the SiI9022 (and implicitly EDID I2C) device to the ARM
Versatile Express machine, and selects the two I2C devices necessary
in the arm-softmmu.mak configuration so everything will build
smoothly.
I am implementing proper handling of the graphics in the Linux
kernel and adding proper emulation of SiI9022 and EDID makes the
driver probe as nicely as before, retrieving the resolutions
supported by the "QEMU monitor" and overall just working nice.
