Subject: PCI: Deprecate pci_reset_bus() and pci_reset_slot() functions
Patch-mainline: v4.19-rc1
Git-commit: fe32e2fa656c29d5d25f959f8e6168ac405d9ab4
References: bsc#1114685 FATE#325854

pci_reset_bus() and pci_reset_slot() functions are not being used by any
code.  Remove them from the kernel in favor of pci_try_reset_bus() and
pci_try_reset_slot() functions.
