Ard Biesheuvel 47ba5f39ea ARM: entry: Make asm coproc dispatch code NWFPE only
Now that we can dispatch all VFP and iWMMXT related undef exceptions
using undef hooks implemented in C code, we no longer need the asm entry
code that takes care of this unless we are using FPE, so we can move it
into the FPE entry code. As this means it is ARM only, we can remove the
Thumb2 specific decorations as well.

It also means the non-standard, asm-only calling convention where
returning via LR means failure and returning via R9 means success is now
only used on legacy platforms that lack any kind of function return
prediction, avoiding the associated performance impact.
