This patch changes the return instruction in the
tr_32x4 macro from br to ret.
Using ret properly hints that the branch is a
function return.
On devices that support BTI a landing pad is
required when branching with br, or the instruction
can be replaced with a ret.
The change fixes fate-hevc-hdr-vivid-metadata when
on hardware with BTI support.
