xizx c6c98fe6ef touchscreen: dynamic check the goodix device status
Kernel should not allow two drivers to assign same irq resource,
or else it will cause unknown irq storm issue.

For goodix touch driver, the i2c device driver will always match
device tree node and request irq resource even goodix touch doesn't
exist at all. When the kernel always loads another touch driver,
such as stmicro fts driver, they will compete the irq responsing and
cause lots of cpu hang issue.

Dynamically check the goodix sensor device status according dts config
to avoid the uncessary register driver.
