Viktor Sjölind 5f51e4a762 pci.c: assert MSIX table count <= config max
Assert that PCI devices discovered while booting the hypervisor do not
have more table entries than allowed by the compile-time configuration
(CONFIG_MAX_MSIX_TABLE_NUM).

The case were `msix.table_count` > `CONFIG_MAX_MSIX_TABLE_NUM` is fatal
since the init function in the handler for MSI-X (vmsix_init) only looks
at `table_count` when populating the table. Since
`CONFIG_MAX_MSIX_TABLE_NUM` is the max size of the table array entry in
the pci_msix struct. This will cause the msix handler to write outside of
the table array.

ACRN Hypervisor
###############

The open source `Project ACRN`_ defines a device hypervisor reference stack and
an architecture for running multiple software subsystems, managed securely, on
a consolidated system by means of a virtual machine manager. It also defines a
reference framework implementation for virtual device emulation, called the
“ACRN Device Model”.

The ACRN Hypervisor is a Type 1 reference hypervisor stack, running directly on
the bare-metal hardware, and is suitable for a variety of IoT and embedded
device solutions. The ACRN hypervisor addresses the gap that currently exists
between datacenter hypervisors, and hard partitioning hypervisors. The ACRN
hypervisor architecture partitions the system into different functional
domains, with carefully selected guest OS sharing optimizations for IoT and
embedded devices.

You can find out more about Project ACRN on the `Project ACRN documentation`_
website.
