Currently tda998x_encoder_destroy() calls cec_write() and reg_clear(), as part of the release procedure. Such calls need to access the I2C bus and therefore, we need to call them before drm_i2c_encoder_destroy() which unregisters the I2C device.
This commit moves the latter so it's done afterwards.
