ARM: dts: msm: Fix home key and qbt1000 configuration for SM8150 platforms

PM8150 GPIO 1 can be connected to either home button or fingerprint
sensor(FPS) on SM8150 platforms. Since there is no home button
present physically on SM8150 MTP/QRD and FPS can be connected
through a connector on need basis, remove home key configuration
from gpio_keys device on them. Since there is a physical home
button on SM8150 CDP to which PM8150 GPIO 1 is connected, keep
FPS (qbt1000) device disabled on it so that it can be enabled
with a proper configuration only when it needs to be used.

Also, move the default pinctrl configuration for PM8150 GPIO 1 to
FPS (qbt1000) device on SM8150 MTP/QRD as that owns the GPIO.
