Merge tag 'samsung-dt-4.4-2' of http://github.com/krzk/linux into v4.4-next/dt-samsung

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