[PATCH 2/2] i2c: mt7621: make device_reset optional

Rely on device_reset_optional() instead of device_reset() in
mtk_i2c_reset routine since Airoha EN7581 reset controller does not
implement the reset callback and device reset is not mandatory on this
SoC. This will remove the following log:

i2c-mt7621 1fbf8000.i2c0: I2C reset failed!
