ANDROID: fix frame buffer device driver modularization issues

Modularizing frame buffer device driver will enable CONFIG_FB_DEVICE,
which will change the member variable dev in the structure fb_info. This
can lead to "disagrees about version of symbol" problems.

This modification was made with the goal of enabling modular frame buffer
device driver support.
