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
v2 (jsmoeller): make changes in virtualization-layer conditional to raspberrypi4
