Subject: [PATCH 4.19 535/639] usb: typec: tps6598x: Fix build error without CONFIG_REGMAP_I2C

From: YueHaibing <yuehaibing@...wei.com>

[ Upstream commit 35af2445dc306403254a181507b390ec9eb725d5 ]

If CONFIG_REGMAP_I2C is not set, building fails:

drivers/usb/typec/tps6598x.o: In function `tps6598x_probe':
tps6598x.c:(.text+0x5f0): undefined reference to `__devm_regmap_init_i2c'

Select REGMAP_I2C to fix this.
