Patch-mainline: v5.7-rc1
Subject: PCI: hv: Move hypercall related definitions into tlfs header
Git-commit: b00f80fcfaa098f987dde99585e73e8ed7edae51
References: bsc#1172871, bsc#1172872
Currently HVCALL_RETARGET_INTERRUPT and HV_PARTITION_ID_SELF are defined
in pci-hyperv.c. However, similar to other hypercall related
definitions, it makes more sense to put them in the tlfs header file.
Besides, these definitions are arch-dependent, so for the support of
virtual PCI on non-x86 archs in the future, move them into arch-specific
tlfs header file.
