Edwin Zhai 30549a59c7 DM: increase vioapic pin count
Current only 8 vioapic pins for pci irq (total 24 with 16 reserved),
which easily leads virtual GSI sharing with more and more passthrough
devices. This patch doulbes vioapic pin count and adds reboot hooks to
allocate from same pin after each reboot.

ACRN Device Model
#################

Introduction
============
The ACRN Device Model provides **device sharing** capabilities between the Service OS and Guest OSs. It is a component that is used in conjunction with the `ACRN Hypervisor`_ and this is installed within the Service OS. You can find out more about Project ACRN on the `Project ACRN documentation`_ website.
