The mmc probing order has become unpredictable
due to recent linux kernel changes, therefore devices
like the raspberry pi that have two mmc interface most
of the time can't boot from the hard-coded root path.
Modify the u-boot script to fetch the PARTUUID of the
second partition of the sd card and use it to put
root=PARTUUID=<xxx> in the command line passed to
the dom0 kernel.

Add a new xen-rpi-u-boot-scr recipe to PROVIDE u-boot-default-script
instead of using a bbappend to rpi-u-boot-scr.
This allows the new recipe to be selected by indicating it as
PREFERRED_PROVIDER of u-boot-default-script, and then do that in the
Xen on Raspberry Pi 4 config file, xen-raspberrypi4-64.inc.
