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

This reverts commit 4596fa7151e10d6d4baff99b07a063890ce043eb.

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.
