platform/x86: intel-vbtn: Fix probe failure on devices with only switches
On some devices the INT33D6 vbtn device is only used to report
tablet-mode / docked status (switches) and there are no vbtn managed
buttons.
On these devices there is no VBDL object.
Move the VBDL check to a intel_vbtn_has_buttons() helper and only exit
from intel_vbtn_probe() with -ENODEV when there are both no buttons and
no switches. Also only report the buttons being present to userspace if
the has_buttons check has succeeded.
