Subject: [PATCH 2/2] power: bq24190: Add BQ24193 support

From: Aaron Kling <webgeek1234@...il.com>

The BQ24193 is most similar to the BQ24192. This is used in many Nvidia
Tegra devices such as the SHIELD Portable. This variant works as-is with
the existing BQ24192 code, but cannot be probed with a simple fallback
compatible to ti,bq24192. So add it same as how BQ24196 is handled.
