[ Upstream commit 5ca505c6b0259606361d8f95b0811b783d4e78f7 ]
Sensors are enabled independently of HID device initialization. Sensor initialization should be kept separate in this case, while HID devices should be initialized according to the sensor state. Hence split sensor initialization and HID initialization into separate blocks.
