Subject: [PATCH v2 1/3] ASoC: simple-card-utils: Support configure pin_name for asoc_simple_init_jack

Currently the pin_name is fixed in asoc_simple_init_jack, but some driver
may use a different pin_name. So add a new parameter in
asoc_simple_init_jack for configuring pin_name.

If this parameter is NULL, then the default pin_name is used.
