[PATCH] net/gve: fix meson build failure on non-Linux platforms

[PATCH] net/gve: fix meson build failure on non-Linux platforms

[Junfeng Guo]

Meson build may fail on FreeBSD with gcc and clang, due to missing
the header file linux/pci_regs.h on non-Linux platform. Thus, in
this patch, we removed the file include and added the used Macros
derived from linux/pci_regs.h.

Fixes: 3047a5ac8e66 ("net/gve: add support for device initialization")
