It bothered to me to see "static struct i2c_algorithm i2c_dw_algo {}"
defined twice both in i2c-designware-pcidrv.c and
i2c-designware-platdrv.c and so many exported i2c-designware-core
functions.
It turned out some of them became unused or are local and there were
also duplicated probe code that I moved to new common i2c_dw_probe().
Object sizes below before and after this set from CONFIG_X86_64=y build.
