powerpc/pseries: plpks: export plpks_wrapping_is_supported

Building trusted-keys as a module fails modpost with:

ERROR: modpost: "plpks_wrapping_is_supported" [security/keys/trusted-keys/
trusted.ko] undefined!

Export plpks_wrapping_is_supported() so trusted-keys links cleanly

This patch is intended to be applied on top of the earlier "Extend "trusted
" keys to support a new trust source named the PowerVM Key Wrapping Module
(PKWM)" series (v5).
