[seL4] Adding Platform Support: CAmkES-ARM-VM: VM_Minimal: Raspberry Pi 3b

Hi, I have been attempting to add support for the Raspberry Pi 3 b platform so that I can run the vm_minimal application on it. The platform supports ARM_HYP, so I believe it should be possible to get this working. I have reached to point where ninja errors on an implicit declaration for `set_gic_vcpu_ctrl_hcr`. From what I understand, this is to do with the ARM Generic Interrupt Controller, however the RPi3b doesn't have a GIC, it has a `bcm2836-armctrl-ic`. This occurs because the file vcpu.h defines an inline function that calls this function, however as the RPi3b doesn't have a GIC, neither the gic_v2.h or gic_v3.h files are provided in the build environment, and hence the build fails. I am unsure what this means in terms of implementation. What needs to be added or changed to get this compiling for the RPi3b?
