(7-bit device address << 1), always leaving the room for the read/write bit. This commit convert ti_i2c and revert r259127 on bcm2835_bsc to make them compatible with 8-bit addresses. Previous to this commit an i2c device would have different addresses depending on the controller it was attached to (by example, when compared to any iicbb(4) based i2c controller), which was a pretty annoying behavior. Also, update the PMIC i2c address on beaglebone* DTS files to match the new address scheme. Now the userland utilities need to do the correct slave address shifting (but it is going to work with any i2c controller on the system). Discussed with: ian MFC after: 2 weeks
