[RESEND PATCH 2/3] ARM: EXYNOS4: Update consistent DMA size to 8MB

[Hatim Ali]

Change the consistent DMA allocation to 8MB to support the
TVOUT driver.

NOTE: Once CMA support is merged into mainline, we will use it for memory
allocation.

Hi,

As I know,  CONSISTENT_DMA_SIZE is removed, please use the updated APIs.

Thank you,

The macro definition CONSISTENT_DMA_SIZE has been removed and has been

Probably, this conflicts with 'Remove define CONSISTENT_DMA_SIZE'. 

As other guy said, we need to check the progress of it before this.

Thanks.

Best regards,
