This adds DDC support to ati-vga and connects i2c-ddc to it. This allows at least MacOS with an ATI ndrv, Linux radeonfb and MorphOS to get monitor EDID info (although MorphOS splash screen is not displayed and radeonfb needs additional tables from vgabios-rv100). Xorg needs additional support from VESA vgabios, it's missing INT10 0x4F15 function (see https://gitlab.freedesktop.org/xorg/xserver/blob/master/hw/xfree86/vbe/vbe.c) without which no DDC is available that also prevents loading the accelerated X driver.
