HID: amd_sfh: Split sensor and HID initialization

Browse Source 
[ Upstream commit 5ca505c6b0 ]

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.
