This fails to build on 32-bit targets because of a missing __udivdi3.
IIRC the right way to fix that is to avoid the division, but I just want
a tree that builds and the only real T-Head platforms are 64-bit right
now.

Sorry about that. This patch makes sense as the TH1520 SoC is 64-bit
and I see no valid use case to run a 32-bit kernel on it.
