i2c: Move bitbang_i2c.h to include/hw/i2c/
The bitbang i2c implementation is also useful for other device models such as DDC in display controllers. Move the header to include/hw/i2c/ to allow it to be used from other device models and adjust users of this include. This also reverts commit 2b4c1125ac which is no longer needed.
