Phase 2: PCI Config Space & BAR Enhancements
- Enhanced PCI config space write handlers in main.c:
- Added MSI-X Message Control (0x72-0x73) write support
- Added MSI-X Table Offset/BIR (0x74-0x77) write support
- Added MSI-X PBA Offset/BIR (0x78-0x7B) write support
- Enhanced BAR emulation in bar_emulation.c:
- Added MSI-X Table emulation (32 entries at BAR0+0x2000)
- Added MSI-X PBA emulation (64-bit at BAR0+0x3000)
- Added nv_vgpu_msix_set_pending/clear_pending for interrupt injection
- Integrated with GSP emulation constants from gsp_emulation.h
- Updated bar_emulation.h with MSI-X struct definitions and function declarations
- Added GSP emulation constants to gsp_emulation.h (MSIX offsets, polling params)
