mb/facebook/fbg1701/devicetree.cb: Use 64MB framebuffer size 

Connected 4K monitor is not configured at max resolution. The
framebuffer size is too small.

Increase the framebuffer size to 64MB. This is sufficient for max
configuration of 1 HDMI monitor combined with internal LCD panel.

BUG=N/A
TEST=4K HDMI monitor and LCD working fine on Facebook FBG-1701
