HV: vuart: enable vuart console for VM

Browse Source 
In previous code, only for pre-launched VM, hypervisor would create
vuart console for each VM. But for post-launched VM, no vuart is
created.
In this patch, create vuart according to configuration in structure
acrn_vm_config. As the new configuration is set for pre-launched VM and
post-launched VM, and the vuart initialize process is common for each
VM, so, remove CONFIG_PARTITION_MODE from vuart related code.
