Device Tree improvements for Exynos based boards (updated pull request):

Browse Source 
1. Enable DMA on Exynos4 serial ports. This old patch uncovered
    a number of other issues in dmaengine and samsung serial driver.
    All of known issues are resolved so finally enable the DMA for UART.
 2. Fix incorrect location of display-timings node (FIMD->DP node)
    on Arndale, SMDK5250 and SMDK5240 boards.
 3. Minor cleanups.
