virt: acrn: Introduce ACRN HSM basic driver ACRN Hypervisor Service Module (HSM) is a kernel module in Service VM which communicates with ACRN userspace through ioctls and talks to ACRN Hypervisor through hypercalls. Add a basic HSM driver which allows Service VM userspace to communicate with ACRN. The following patches will add more ioctls, guest VM memory mapping caching, I/O request processing, ioeventfd and irqfd into this module. HSM exports a char device interface (/dev/acrn_hsm) to userspace.
