pci: avoid accessing slot_reserved_mask directly outside of pci.c
This patch provides accessor functions as replacements for direct access to slot_reserved_mask according to the comment at the top of include/hw/pci/pci_bus.h which advises that data structures for PCIBus should not be directly accessed but instead be accessed using accessor functions in pci.h. Three accessor functions can conveniently replace all direct accesses of slot_reserved_mask. With this patch, the new accessor functions are used in hw/sparc64/sun4u.c and hw/xen/xen_pt.c and pci_bus.h is removed from the included header files of the same two files. No functional change intended. Signed-off-by: Chuck Zmudzinski <brchuckz@aol.com> Message-Id: <b1b7f134883cbc83e455abbe5ee225c71aa0e8d0.1678888385.git.brchuckz@aol.com> Reviewed-by: Michael S.
