GPIO I2C rework Reqrite bitbanging I2C implementation. New code improves stop/start condition handling, and gives more accurate input line level. Introduce intermediate abstraction layer for I2C bitbanging that is not connected via a GPIO port.

hw: move headers to include/ Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
