ITE drivers/kscan: support tests/driver/kscan/kscan_api

Add kscan0 to support tests/driver/kscan/kscan_api.

When running the tests code on it8xxx2_evb, it shows fatal
error: IRQ is enabled. We find that once polling_task() is
created and executed, the KSI interrupt will be enabled and
before we call irq_connect_dynamic(), so we switch both
function sequence.
