Ard Biesheuvel 17df190b6a crypto: arm64/poly1305-neon - reorder PAC authentication with SP update 
[ Upstream commit 519a0d7e495a6d3ce62594e485aea2a3a4a2ca0a ]

PAC pointer authentication signs the return address against the value
of the stack pointer, to prevent stack overrun exploits from corrupting
the control flow. However, this requires that the AUTIASP is issued with
SP holding the same value as it held when the PAC value was generated.
The Poly1305 NEON code got this wrong, resulting in crashes on PAC
capable hardware.
