[PATCH 07/15] power: supply: bq24190_charger: Add support for bq24192[i]

The bq24192 and bq24192i are mostly identical to the bq24190, TI even
published a single datasheet for all 3 of them. The difference
between the bq24190 and bq24192[i] is the way charger-type detection
is done, the bq24190 is to be directly connected to the USB a/b lines,
where as the the bq24192[i] has a gpio which should be driven high/low
externally depending on the type of charger connected, from a register
level access pov there is no difference.

The differences between the bq24192 and bq24192i are:
1) Lower default charge rate on the bq24192i
2) Pre-charge-current can be max 640 mA on the bq24192i

Since we do not provide an API for setting the pre-charge-current,
these differences can be ignored and we can simply use the existing
code as-is with the bq24192 and bq24192i.
