[PATCH v2 20/32] hw/arm: phytium: Add Phytium E2000 xHCI controllers

[Bin Meng <bin.meng@processmission.com>]

Instantiate two sysbus xHCI controllers at the documented addresses
and wire their single interrupts to the GIC. Match the platform quirk
by disabling streams and expose one paired USB 2.0/3.0 root port per
controller.

Signed-off-by: Bin Meng <bin.meng@processmission.com>

Changes in v2:
- Move the xHCI controllers into the E2000 SoC
