Subject: [PATCH 4.14 112/191] i2c: rcar: Auto select RESET_CONTROLLER

From: Dirk Behme <dirk.behme@...bosch.com>

[ Upstream commit 5b9bacf28a973a6b16510493416baeefa2c06289 ]

The i2c-rcar driver utilizes the Generic Reset Controller kernel
feature, so select the RESET_CONTROLLER option when the I2C_RCAR
option is selected with a Gen3 SoC.
