[PATCH v6 10/11] hw/arm/aspeed_ast27x0: Enable 64-bit EHCI DMA addressing

[Jamin Lin <jamin_lin@aspeedtech.com>]

AST2700 supports a 64-bit DRAM address space. Therefore, DMA
transactions must be capable of accessing 64-bit addresses.

Enable the "caps-64bit-addr" property for the EHCI controllers
on AST2700 so that USB DMA operations can correctly handle
64-bit memory addresses.
