remoteproc/mediatek: Remove non-standard dsb() 

As reported by Stephen, dsb() is not declared on e.g. x86_64, preventing
the mtp_scp from building. Simply remove the barrier (and the readback),
suggested by Pi-Hsun to resolve this.

Fixes: fd0b6c1ff8 ("remoteproc/mediatek: Add support for mt8192 SCP")
