linux (Allwinner): i2c: move to .probe_new() call-back type

Browse Source 
since kernel 4.10-rc1 .probe_new has been availble as a prototype.
from kernel 6.3-rc2 the old prototype which included a i2c_device_id variable has now dropped this variable.

update the AC200 patch to use .probe_new which will allow this patch to compile against kernels >= 4.10

in future - the patch can be updated to use .probe (but will loose compatibilty with kernels <= 6.3.)
