Functions hv_read_config_block(), hv_write_config_block()
and hv_register_block_invalidate() are not used anywhere
else and are local to drivers/pci/controller/pci-hyperv.c,
and do not need to be in global scope, so make these static.
Resolve following compiler warning that can be seen when
building with warnings enabled (W=1):
drivers/pci/controller/pci-hyperv.c:933:5: warning: no previous prototype for ‘hv_read_config_block’ [-Wmissing-prototypes]
int hv_read_config_block(struct pci_dev *pdev, void *buf, unsigned int len,
^
drivers/pci/controller/pci-hyperv.c:1013:5: warning: no previous prototype for ‘hv_write_config_block’ [-Wmissing-prototypes]
int hv_write_config_block(struct pci_dev *pdev, void *buf, unsigned int len,
^
drivers/pci/controller/pci-hyperv.c:1082:5: warning: no previous prototype for ‘hv_register_block_invalidate’ [-Wmissing-prototypes]
int hv_register_block_invalidate(struct pci_dev *pdev, void *context,
^
