Subject: [PATCH v4 02/12] vfio_pci: move vfio_pci_is_vga/vfio_vga_disabled to header file

This patch moves two inline functions to vfio_pci_private.h for further
sharing across source files. Also avoids below compiling error in further
code split.

"error: inlining failed in call to always_inline ‘vfio_pci_is_vga’:
function body not available".
