For some reason those targets have quite imprecise button voltages and the
old margin was too small. This should fix the button-not-working issue,
especially when the player is very hot and cold.

Apparently the backlight driver is leaking current even when the PWM set to 0.
This patch should greatly improve the battery life of the device.

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
