drm/amd/powerplay: skip smu_i2c_eeprom_init/fini under sriov mode

When smu_i2c_eeprom_init is called on the smu resuming process
under sroiv mode, there will be a call trace:

This is because smu_i2c_eeprom is not released on gpu recovering.
Actually, smu_i2c_eeprom_init/fini are only needed under bare
mental mode.
