Patch-mainline: v5.9-rc1
Subject: PCI: hv: Make some functions static
Git-commit: a459d9e107887a1fef32d5c6d0951241876812d9
References: jsc#sle-12891

sparse report build warning as follows:

drivers/pci/controller/pci-hyperv.c:941:5: warning:
 symbol 'hv_read_config_block' was not declared. Should it be static?
drivers/pci/controller/pci-hyperv.c:1021:5: warning:
 symbol 'hv_write_config_block' was not declared. Should it be static?
drivers/pci/controller/pci-hyperv.c:1090:5: warning:
 symbol 'hv_register_block_invalidate' was not declared. Should it be static?

Those functions are not used outside of this file, so mark them static.
