extcon: sm5502: Add support for SM5703

Browse Source 
SM5703 is another MFD from Silicon Mitus which has a very similar MUIC
unit to the one in SM5502. The only difference I've noticed is slightly different
configuration only enables the interrupts which are exactly the same as on SM5502.
If we make use of different interrupts in the future, this can be improved by having
a separate struct for SM5703, but the main functionality (detecting cable or OTG adapter)
is working properly.
