drivers/can: Remove CAN_FILTER_DATA on zephyr

In Zephyr, with PR below, `CAN_FILTER_DATA` and `CAN_FILTER_RTR`
have been removed.

  - zephyrproject-rtos/zephyr#67127

Originally, `CAN_FILTER_DATA` was specified explicitly to filter CAN
Data Frames, but in reality, in the Zephyr driver, it is possible
to filter CAN Data Frames without specifying `CAN_FILTER_DATA`.
Therefore, in this commit, `CAN_FILTER_DATA` is removed.
