Subject: [PATCH] arm64: neon/efi: Make EFI fpsimd save/restore variables
 static

Git-commit: 3b66023d574fee8a481f8e4e1b5bd15583a3b5bf
Patch-mainline: v4.14-rc1
References: fate#325866

The percpu variables efi_fpsimd_state and efi_fpsimd_state_used,
used by the FPSIMD save/restore routines for EFI calls, are
unintentionally global.

There's no reason for anything outside fpsimd.c to touch these, so
this patch makes them static (as they should have been in the first
place).
