On x86 platform, the upper 16 bit of I/O BAR should be initialized to
zero by BIOS. Howerever, some buggy BIOS still programs the upper 16
bits to non-zero, which causes error in check_pt_dev_pio_bars(). Since
I/O BAR reprogramming by VM is currently unsupported, this patch
ignores such I/O BARs when creating vpci devices to make VM boot.

When guest traps and wants to access a mmio region, the ACRN hypervisor
doesn't know the mmio size the guest wants to access until the trap
happens. In this case, ACRN should switch the mmio size and then call
mmio_read8/16/32/64 or mmio_write8/16/32/64 in each trap place.
This patch wrap the mmio read/write with a parameter to assign the mmio
size.

Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

Instead of "#include <x86/foo.h>", use "#include <asm/foo.h>".
In other words, we are adopting the same practice in Linux kernel.
