platform/x86: lenovo-ymc: Ignore the 0x0 state
[ Upstream commit d9dca215708d32e7f88ac0591fbb187cbf368adb ]
While booting, Lenovo 14ARB7 reports 'lenovo-ymc: Unknown key 0 pressed'
warning. This is caused by lenovo_ymc_probe() calling lenovo_ymc_notify()
at probe time to get the initial tablet-mode-switch state and the key-code
lenovo_ymc_notify() reads from the firmware is not initialized at probe
time yet on the Lenovo 14ARB7.
The hardware/firmware does an ACPI notify on the WMI device itself when
it initializes the tablet-mode-switch state later on.
Add 0x0 YMC state to the sparse keymap to silence the warning.
