Device: declare device as specific acccess mode

Some drivers like EEPROM, should not be written to.
Even though we didn't use write access mode from userspace,
it still needs to guard this situation from other testing
in kernel such as Fuzzing.

Use device tree property to conduct device as read only or others.
