[PATCH] [3.3] [RESEND] ARM: tegra: fuse: use apbio dma for register access

[Olof Johansson]

Use the apbio dma functions for accessing the fuse registers.

Signed-off-by: Olof Johansson <olof at lixom.net>

Resend due to messed up linux-arm-kernel address.

This patch depends on "ARM: tegra: use APB DMA for accessing APB devices",
I forgot to send them as a 2-patch series.
