It turns out Longcheer L8150 actually has a BMC156 which is very similar to BMC150, but only has an INT2 pin for the accelerometer part. This requires some minor changes in the bmc150-accel driver which is now supported by using the more correct bosch,bmc156_accel compatible. Unfortunately it looks like even INT2 is not functional on most boards because the interrupt line is not actually connected to the BMC156. However, there are two pads next to the chip that can be shorted to make it work if needed. While at it, add the missing interrupts for the magnetometer part and extra BMG160 gyroscope, those seem to work without any problems. Also correct the magnetometer compatible to bosch,bmc156_magn for clarity (no functional difference for the magnetometer part).
