Raspberry 4: XEN support

Added the support for DOM0 in raspberry pi4. The feature agl-virt-xen should be enabled to activate this code.

1512 MB of memory is used for DOM0 machine.

There are limitations:
	- brcmfmac module disabled (bluethooth and Wifi) due to the crash
	- total_memory is set to the 3Gb, as it impacts the USB ports on rasbperry pi4 on Linux kernel 4.19
