[PATCH v3 2/8] DMA: Freescale: unify register access methods

[David Laight]

From: hongbo.zhang at freescale.com
> Methods of accessing DMA contorller registers are inconsistent, some registers
                               ^^
> are accessed by DMA_IN/OUT directly, while others are accessed by functions
> get/set_* which are wrappers of DMA_IN/OUT, and even for the BCR register, it
> is read by get_bcr but written by DMA_OUT.
> This patch unifies the inconsistent methods, all registers are accessed by
> get/set_* now.
