USB: ehci-s5p: add DMA burst support DMA burst support is added to improve performance in EHCI data transfer. The USB EHCI controller on Exynos SoCs can use INCR16, INCR8, and INCR4 mode. These modes of INSNREG00 register should be set in order to enable DMA burst transfer. This feature is also related to AHB spec.
