ASoC: renesas: rz-ssi: Fix channel swap issue in full duplex mode

Browse source

commit 52a525011c upstream.

The full duplex audio starts with half duplex mode and then switch to
full duplex mode (another FIFO reset) when both playback/capture
streams available leading to random audio left/right channel swap
issue. Fix this channel swap issue by detecting the full duplex
condition by populating struct dup variable in startup() callback
and synchronize starting both the play and capture at the same time
in rz_ssi_start().
