ARM: dts: msm: Set vCPU affinity to CPU0 for VMs on Tuna

Browse Source 
Even though we use proxy scheduling, during VM bootup hypervisor tries
to boot the VMs as per the affinity-map. This may cause panic in case a
CPU within affinity-map is unavailable.

Affining vCPUs to CPU0 makes sure VM proceeds with
powered-ON sequence, assuming CPU0 is always available.
