[PATCH] platform/x86: lenovo-ymc: Ignore the 0x0 state

[Gergo Koteles]

While booting, Lenovo 14ARB7 reports 'lenovo-ymc: Unknown key 0 pressed'
warning. Because lenovo_ymc_probe() calls lenovo_ymc_notify() and that
time the YMC part is not triggered yet (which is mandatory for this
model). At the end of lenovo_ymc_notify() YMC is triggered by the
ideapad-laptop driver and then lenovo_ymc_notify() will be called by WMI
to report the actual value.

Add 0x0 YMC state to the sparse keymap to ignore.
