Subject: [PATCH 01/34] powerpc/fsl-soc: hide unused const variable

From: Arnd Bergmann <arnd@...db.de>

vmpic_msi_feature is only used conditionally, which triggers a rare
-Werror=unused-const-variable= warning with gcc:

arch/powerpc/sysdev/fsl_msi.c:567:37: error: 'vmpic_msi_feature' defined but not used [-Werror=unused-const-variable=]
  567 | static const struct fsl_msi_feature vmpic_msi_feature =

Hide this one in the same #ifdef as the reference so we can turn on
the warning by default.

Fixes: 305bcf26128e ("powerpc/fsl-soc: use CONFIG_EPAPR_PARAVIRT for hcalls")
