Subject: [PATCH v2] PCI: hv: Make functions only used locally static in pci-
hyperv.c

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,
     ^
