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.
