This change avoids DMA error in the cases where dma_mask and
coherent_dma_mask of a 32-bit controller get configured as
DMA_BIT_MASK(64) when running on a 64-bit system.

The xhci platform driver does not work with system that only supports
64-bit DMA as it requests 32-bit DMA mask during driver initialization.
This patch set addresses this issue and also adds XHCI-compliant USB
Controller ACPI identification into xhci-platform driver.

gt; Care to repost the whole patch updated?
I tested this v3 patch set with 4.2-rc5 and it works fine on my X-Gene
arm64 platform.
The only problem is 'git am' will complain (due to line offset
changed, I guess). Using 'patch -p 1' to apply the 2 patches is fine.
I will repost the whole set over 4.2-rc5.
