asm-generic: Define 'func_desc_t' to commonly describe function descriptors
We have three architectures using function descriptors, each with its
own type and name.
Add a common typedef that can be used in generic code.
Also add a stub typedef for architecture without function descriptors,
to avoid a forest of #ifdefs.
It replaces the similar 'func_desc_t' previously defined in
arch/powerpc/kernel/module_64.c
