usb: ehci: Add Aspeed AST2700 support
Unlike earlier Aspeed SoCs (AST2400/2500/2600) which are limited to
32-bit DMA addressing, the EHCI controller in AST2700 supports 64-bit
DMA. Update the EHCI platform driver to make use of this capability by
selecting a 64-bit DMA mask when the "aspeed,ast2700-ehci" compatible
is present in device tree.
