ARM: dts: am335x-sl50: Fix audio bitclock and frame master endpoint
The cpu_endpoint in mcasp0 specifies the TLV320AIC3106 codec as the
bitclock and frame master, but the phandles point to the codec's port
node (codec_port) rather than its endpoint node (codec_endpoint).
audio-graph-card calls simple_util_parse_daifmt() with ep_codec set to
the endpoint node (codec_endpoint). The function resolves the
bitclock-master phandle and checks whether it equals ep_codec. Since
codec_port is the parent of codec_endpoint, not the endpoint itself, the
comparison always evaluates to false. This causes the mcasp0 CPU side to
be silently configured as bitclock and frame master instead of the codec,
which is the opposite of the intended configuration.
Fix by pointing bitclock-master and frame-master to codec_endpoint.
