Revert "mfd: cros_ec: Add ACPI GPE handler for LID0 devices"

This reverts commit feac9f985f73feb9db0f6514983345385a851530.

It is no longer needed to install Chrome EC GPE handler to have
GPE enabled in suspend to idle path. It is found that with this
handler installed, EC wake up doesn't work because default EC
event handler that can wake up system is not getting called.
