[PATCH BlueZ 1/2] input: fix HID compilation w/o HoG

[Thomas Perale <thomas.perale@xxxxxxx>]

Commit [1] introduced a dependency with the HID plugin in the HoG code
As a result, building with --enable-hid --disable-hog caused linker
errors due to undefined references to HoG-related functions:

```
> ./configure --enable-hid --disable-hog
...
> make
...
  CCLD     src/bluetoothd
/usr/bin/ld: profiles/input/bluetoothd-manager.o: in function `input_init':
/home/../bluez/profiles/input/manager.c:122:(.text.input_init+0x1c8): undefined reference to `input_set_auto_sec'
collect2: error: ld returned 1 exit status
make[1]: *** [Makefile:6376: src/bluetoothd] Error 1
```

This patch moves the `input_set_auto_sec` function to
`profiles/input/device.c` file so it remains defined even when HoG is
disabled.
