i2c: designware_i2c: Don't warn if no reset controller
At present if CONFIG_RESET is not enabled, this code shows a warning:
designware_i2c_ofdata_to_platdata() i2c_designware_pci i2c2@16,0:
Can't get reset: -524
Avoid this by checking if reset is supported, first.
Fixes: 622597dee4f ("i2c: designware: add reset ctrl to driver")
