Android: Make lcd updates synchronous, doesn't make it faster but smoother (no updates are skipped) and guaranteed to be glitch free.
test_fps can also now report reasonable numbers: ~62 fps for both 1/1 and 1/4 updates (was 300-400 previously). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@28728 a1c6a512-1295-4272-9138-f99709370657
