[ALSA] hda-codec - Fix the initial mixer state of ALC262 sony-assamd model

Many of ALC262 codes don't call the automute function at the beginning,
which may keep the silence until the HP jack is replugged.  Now proper
init_hook is added.
Also, sony-assamd model doesn't handle the widget 0x14 properly, thus
calling automute isn't enough.  Now Front switch handles both widgets.
