i2c: designware: Initialize adapter name only when not set

Browse source 
Check if the adapter name is already set in the driver prior to
initializing with generic name in i2c_dw_probe_master(). This
check allows to retain the unique adapter name driver has
initialized, which platform driver can use to distinguish it
from other i2c designware adapters.
