This is better style since it has us obtaining all resources before we
try the ASoC probe. This change also fixes a potential issue where we
don't enable the regulators before trying to confirm the device ID which
could cause a failure during probe in some system configurations.

Better style as we acquire resources before trying the ASoC card probe.
Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

Long term all drivers should be using regmap directly. This is more
idiomatic and moves us towards the removal of the ASoC level cache
code.

The initialiasation of reserved register bits in probe() is slightly odd
as the defaults being written don't appear to match the silicon defaults
but the new code should have the same effect as the old code.

The watchdog code will now unconditionally do a mute and unmute when
resyncing but since we only sync when we are very sure there is something
to sync this should have no impact.

The WM0010 is a compact digital signal processor that has been

resources and core optimisation allow the device to manage all audio
processing algorithms efficiently and autonomously, while the host
processor sleeps or performs other tasks.

Currently the microphone input source is not selectable as while there is
a DAPM widget it's not connected to anything so it won't be properly
instantiated. Add something more correct for the input structure to get
things going, even though it's not hooked into the rest of the routing
map and so won't actually achieve anything except allowing the relevant
register bits to be written.
