Platforms/AMD/CelloBoard: add Renesas PD72020x firmware uploader

The Renesas PD720202 controller on the Celloboard does not include
an external ROM to contain the device firmware, and so it is up to
the system firmware to upload such a device firmware before the XHCI
driver can attach to it.

In order to build the Cello firmware with this driver enabled, the
RENESAS_XHCI_FW_DIR define needs to be set to the location of the
firmware file 'K2013080.mem'
