Currently, vfio device fails to initialize as the msix-cap region in BAR is mapped as RW region. To resolve the initialization issue, this commit avoids mapping the msix-cap region in the BAR. However, this solution introduces another problem where aligning the msix table offset in the BAR to the page size may cause overlap with the MMIO RW region, leading to reduced performance. By enlarging the entire region in the BAR and relocating the msix table to achieve page size alignment, this problem can be overcomed effectively.
