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: fd0b6c1ff85a ("remoteproc/mediatek: Add support for mt8192 SCP") Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Suggested-by: Pi-Hsun Shih <pihsun@chromium.org> Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
