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.
