overlays/mtk: Add back Cadence-removed macro

andyross · stephanosio · commit 71442725ec0c · 2024-12-10T07:37:56.000+09:00
There is no "predicted branches" extension in any version of the
Xtensa ISA reference I have.  Newer versions of Cadence tooling have
removed (and presumably deprecated) this symbol, but binutils still
relies on seeing it (even just to evaluate to a zero to diable the
feature).

Really the proper fix would be to patch binutils upstream, but let's
have compatible headers here first.
