In most devices, the button ladder is not actually derived from VDDIO but
from a constant voltage source, making it very easy to read it. However on
some devices like ther ZEN X-Fi Style, the ladder is wired to VDDIO we
can be changed so it's crucial that the button driver correctly scales the
values wrt VDDIO.

The ZEN/ZEN-XFi seem to be very picky about the lcd. And they do not like
standby mode so I'm going to drop it, the OF doesn't use it anyway. I still
don't know what this "power" pin is about, obviously it's not real power but
the OF toggle it. Let's hope the lcd will finally become more stable with
fix: the driver now does full power on/off on enable/disable.

Choices are limited for those: i2c is either generic software or imx233
hardware and power is either none or with a gpio. So factor ever possible
combination in a single common file and use fmradio-target.h to supply the
required parameters. This will remove a bunch of duplicate code.

The old code allowed each target to specify its adc targets but this proved
useless since the target rely directly on imx233/lradc for input method and
generic adc is mostly used for battery and debug. Remove all target specific
files and provide a generic implemenation. The targets can still specify a
battery temperature channel in powermgmt-target.h

Although there is no difference in the cost of a full or partial update,
it is preferable that the semantic of lcd_update_rect() be correct.
