Now that the necessary tweaks for the Aspeed variant of UHCI
are supported, this adds the USB controllers to the DT
template of the AST24xx and AST25xx SoCs.
The EHCI works with the current unmodified driver.
This patch doesn't enable them by default on any board specific
.dts yet. This will be done when we have the necessary clock/reset
and pinmux support. In the meantime though, this will work if
u-boot configures things properly.
