This patch enables fetching configuration data, which is normally provided
via platform_data, from the device-tree instead.
If the device is configured from device-tree data, the platform_data struct
is not used, and button data needs to be allocated dynamically. Big part of
this patch deals with confining pdata usage to the probe function, to make
this possible.

Currently, battery drivers also use poll_sample() provided by the
wm97xx-core but this code always checks if the pen is down. Mark the
channels which really need this (i.e. for the touchscreen) with the
PEN_DOWN bit, and skip the checks otherwise. Now, the battery channels
can always be read.

The current implementation of poll_sample() has the problem that one of
its arguments, the channel to be selected, differs from wm9713 to other
variants. This parameter gets passed to the (currently unused)
mach-specific functions pre_sample() and post_sample() which thus have
to deal with codec-specific differences. Refactor the routine so that
the argument to poll_sample() is generic for all codecs and do necessary
conversions only in the codec-specific driver. The outcome even uses
less code and removes the non-standard use of the PEN_DOWN bit to mark
the AUX-channels.
