a2664f884c xen, rpi4: fix u-boot script to load binaries from boot partition
fatload needs to read from mmc 1:1 to find the Xen hypervisor and Linux
kernel binaries with the current Yocto Linux 5.10 kernel.

Add boot messages to to the u-boot script to indicate the size of files
loaded for easier confirmation of load success.

90a01fcbd9 xen, raspberry pi: add dynamic-layer for Xen configuration for Rpi4
A Xen-specific u-boot script is needed for launching Xen, and the GIC
(interrupt controller) needs to be enabled.

Since this is both Xen-specific and Raspberry Pi-specific, use a
dynamic layer to conditionally enable the recipes when both
meta-virtualization and meta-raspberrypi are in use together.
