Ivshmem device defines four registers including Interrupt Mask, Interrupt
Status, IVPostion and Doorbell. The first two are useless and no emulation
is required. The latter two are used for interrupts and will be implemented
in the future.
This patch also introduces a new priv_data member for structure pci_vdev,
it can be used to find an ivshmem device through pci_vdev.
v2: refine code style
v3: 1) add @pre for ivshmem_mmio_handler function
2) refine code style
v4: 1) set ivshmem registers default value when vBAR mapping
2) change find_ivshmem_device to set_ivshmem_device
v5: 1) change set_ivshmem_device to find_and_set_ivshmem_device
2) add a ASSERT to check if the vdev->priv_data is set successfully
v6: change find_and_set_ivshmem_device to create_ivshmem_device

this patch implements ivshmem device configuration space initialization

v2: introduce init_one_pcibar interface to simplify BAR initialization
operation of HV emulated PCI device.
v3: 1) due to init_one_pcibar API is only used for pre-launched VM vdevs
it can't be applied to all vdevs, so remove it.

There's a corner case:
When want to get CPUID.01H:EDX value,
may have the following code snippet:
uint32_t unused,edx;
cpuid_subleaf(0x1U, 0x0U, &unused, &unused, &unused, &edx);
while in cpuid_subleaf:
*eax = leaf;
*ecx = subleaf;
eax and ecx point to the same location,
When deep into asm_cpuid, it's input value will be 0x0U and 0x0U.
but the expected input value is 0x1U and 0x0U.
This case will return CPUID.00H:EDX, which is the wrong answer.

This patch will move the VM configuration check to pre-build stage,
a test program will do the check for pre-defined VM configuration
data before making hypervisor binary. If test failed, the make
process will be aborted. So once the hypervisor binary is built
successfully or start to run, it means the VM configuration has
been sanitized.
The patch did not add any new VM configuration check function,
it just port the original sanitize_vm_config() function from cpu.c
to static_checks.c with below change:
1. remove runtime rdt detection for clos check;
2. replace pr_err() from logmsg.h with printf() from stdio.h;
3. replace runtime call get_pcpu_nums() in ALL_CPUS_MASK macro
with static defined MAX_PCPU_NUM;
4. remove cpu_affinity check since pre-launched VM might share
pcpu with SOS VM;
The BOARD/SCENARIO parameter check and configuration folder check is
also moved to prebuild Makefile.
