aarch64/hevc: Replace br return with ret
This patch changes the return instruction in the tr_32x4 macro from
BR to RET.
Function returns should always use the RET instruction instead of BR,
to avoid interfering with branch prediction.
On devices that support BTI, this is observeable as a landing pad is
required when branching with BR. The change fixes
fate-hevc-hdr-vivid-metadata when on hardware with BTI support.
