platform/x86: intel-vbtn: Detect switch position before registering the input-device
Setting the initial state of input-device switches must be done before
registering the input-device.
Otherwise the initial state will get send out as an event as soon
as input_sync() gets called.
E.g. when undocking a tablet using intel-vbtn to report SW_TABLET_MODE
and SW_DOCK before this commit we would get (evemu-record output):
E: 0.000001 0005 0005 0001 # EV_SW / SW_DOCK 1
E: 0.000001 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000109 0005 0005 0000 # EV_SW / SW_DOCK 0
E: 0.000109 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms
E: 0.000133 0005 0001 0001 # EV_SW / SW_TABLET_MODE 1
E: 0.000133 0000 0000 0000 # ------------ SYN_REPORT (0) ---------- +0ms
The first SW_DOCK=1 report is spurious, setting the initial switch
state before registering the input-device fixes this.
