This patch changes the return instruction in the
tr_32x4 macro from br to ret.
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.

Hi,
The use of RET vs BR also has microarchitectural side effects. AFAIU, RET
should always be paired with an earlier BL/BLR to avoid interfering with branch
prediction.
So depending on the circumstances, either one of these should be addressed:

Change some internal APIs a bit to make it harder to make
such mistakes.
In particular, have the read chunk functions return an error
when the result is incomplete.
This might be less flexible, but since there has been no
