[PATCH] powerpc: ignore the pkey system calls for now

[Stephen Rothwell]

Eliminates warning messages:

<stdin>:1316:2: warning: #warning syscall pkey_mprotect not implemented [-Wcpp]
<stdin>:1319:2: warning: #warning syscall pkey_alloc not implemented [-Wcpp]
<stdin>:1322:2: warning: #warning syscall pkey_free not implemented [-Wcpp]

Hopefully we will remember to revert this commit if we ever implement
them.
