[PATCH 1/2] hw/arm/xilinx_zynq: Fix USB port instantiation

[Guenter Roeck]

USB ports must be instantiated as TYPE_CHIPIDEA to work.
Linux expects and checks various chipidea registers, which
do not exist with the basic ehci emulation.

Without this patch, USB ports fail to instantiate under Linux.

ci_hdrc ci_hdrc.0: doesn't support host
ci_hdrc ci_hdrc.0: no supported roles

With this patch, USB ports are instantiated, and it is possible
to boot from USB drive.

ci_hdrc ci_hdrc.0: EHCI Host Controller
ci_hdrc ci_hdrc.0: new USB bus registered, assigned bus number 1
ci_hdrc ci_hdrc.0: USB 2.0 started, EHCI 1.00
usb 1-1: new full-speed USB device number 2 using ci_hdrc
usb 1-1: not running at top speed; connect to a high speed hub
usb 1-1: config 1 interface 0 altsetting 0 endpoint 0x81 has invalid maxpacket 
512, setting to 64
usb 1-1: config 1 interface 0 altsetting 0 endpoint 0x2 has invalid maxpacket 
512, setting to 64
usb-storage 1-1:1.0: USB Mass Storage device detected
scsi host0: usb-storage 1-1:1.0
