drm/i915/pxp: fix undefined reference to `intel_pxp_gsccs_is_ready_for_sessions'

Browse Source 
[ Upstream commit 7e21ea8149a0e41c3666ee52cc063a6f797a7a2a ]

On x86_64 with gcc version 13.3.0, I compile kernel with:

  make defconfig
  ./scripts/kconfig/merge_config.sh .config <(
    echo CONFIG_COMPILE_TEST=y
  )
  make KCFLAGS="-fno-inline-functions -fno-inline-small-functions -fno-inline-functions-called-once"

Then I get a linker error:

  ld: vmlinux.o: in function `pxp_fw_dependencies_completed':
  kintel_pxp.c:(.text+0x95728f): undefined reference to `intel_pxp_gsccs_is_ready_for_sessions'

This is caused by not having a intel_pxp_gsccs_is_ready_for_sessions()
header stub for CONFIG_DRM_I915_PXP=n. Add it.
