Subject: [PATCH] platform/x86: lenovo-yogabook: add I2C dependency

From: Arnd Bergmann <arnd@...db.de>

The added platform_driver support fails to link when I2C core support is
not rechable:

x86_64-linux-ld: drivers/platform/x86/lenovo-yogabook.o: in function `yogabook_pdev_probe':
lenovo-yogabook.c:(.text+0x5a5): undefined reference to `i2c_bus_type'

Add a Kconfig dependency to enforce a working configuration.

Fixes: 6df1523fa0b7 ("platform/x86: lenovo-yogabook: Add platform driver support")
