hw/arm: ast27x0: Wire up EHCI controllers

Browse source 
AST27x0 has 4 EHCI controllers, where each CPU and I/O die has 2
instances. This patch use existing TYPE_PLATFORM_EHCI. After wiring up
the EHCI controller, the ast2700a1-evb can find up to 4 USB EHCI
interfaces.

Note that, AST27x0A0 only has 2 EHCI controllers due to hw issue.
