02184a242e make fmradio-i2c code from clip more generic, so it works for m200v4 and hopefully all other as3525 targets.

58eb784a5d Straighten out some powermanagement stuff. Give target complete control over how power inputs are sensed. Clean SIMULATOR stuff out of target files. Get rid of USB charging option on targets that don't support it or don't implement it yet. Menu string remains to avoid language incompatibility but should be removed on next cleanup for targets not using it (notice in english.lang). global_settings becomes incompatible for some builds and so plugin API version is incremented.

50519416ca Sansa Clip : save one instruction per 8 pixels loop in lcd_grey_data 
We set directly the needed bits to write into DBOP_DOUT (15:13 and 3:0)
Since we can't set the mask 0xf00f with one mov instruction, revert the
logic and use orrne instead of biceq (in the whole function for consistency)
