CHROMIUM: Assign the frame buffer address as FDT one instead of u-boot one.
The framebuffer address should be specified in the device tree and not u-boot
assigned. This FDT value should be the same as the one defined in Linux kernel;
otherwise, it causes screen flicker. The FDT value overrides the framebuffer
allocated at the top of memory by board_init_f().
If the framebuffer address is not defined in the FDT, falls back to use the
address allocated by board_init_f().
BUG=chrome-os-partner:5338
TEST=build without error and boot Chrome OS on Aebl, see the screen not
corrupted and splash screen showed.
