powerpc: Use 'struct func_desc' instead of 'struct ppc64_opd_entry'

Browse Source 
'struct ppc64_opd_entry' is somehow redundant with 'struct func_desc',
the later is more correct/complete as it includes the third
field which is unused.

So use 'struct func_desc' instead of 'struct ppc64_opd_entry'
