Check if the chip has provided a write operation (which is mandatory for
I/O) rather than looking for control data as some of the MFDs use a global
for this. Also skip the attempt if there's no regmap available by device
in case things get confused by the attempt to default.

Since commit 38cbf959
("ASoC: core: Try to use regmap if the driver doesn't set up any I/O")
any ASoC codec which doesn't set codec::control_data is assumed
to use regmap.  That doesn't work with AC97 so this workaround
sets the codec::control_data member to a random value to restore
proper behaviour.

Tested with WM9712.

There's a driver bug that sgtl5000 dapm widget kcontrols do not work.
e.g. can not select capture mux with amixer tool(no error info prompted).

The root cause is that we still call snd_soc_dapm_new_widgets in
codec driver probe function afer converting to table based widgets.
This will cause the card dapm widgets are instantiated before the
dapm_routes are registered.
Then, no available dapm widget pathes can be found during instantiation
which finally will cause soc_dapm_mux_update_power to fail(can not find
correct path with kcontrol) in snd_soc_dapm_put_enum_double function.

Here we remove the unneeded snd_soc_dapm_new_widgets in codec probe
and let the soc core to handle the register sequence properly.
Then we can fix above issue.

Currently we directly call a clock_enable in trigger function without
a clk_prepare as pair first.
This will cause system hang immediately when run capture because
the clock was not prepared(playback does not hang because the clock was
prepared already by get_mclk before), a warning message in clock framework
may cause a deadlock to reclaim clock lock (see: pl011_console_write).

Here we prepare clock first in hw_param, then enable it in trigger
function to guarantee the balance.

Ever since the DAPM performance improvements we've been marking all widgets
as not dirty after each DAPM run. Since _PRE and _POST events aren't part
of the DAPM graph this has rendered them non-functional, they will never be
marked dirty again and thus will never be run again.

Fix this by skipping them when marking widgets as not dirty.
