[PATCH] watchdog: iTCO_wdt: Fix unmet dependency in select

[Jean Delvare <jdelvare@suse.de>]

ITCO_WDT selects I2C_I801 but does not select its dependencies (I2C.)
This can result in link-time failures:

drivers/built-in.o: In function `i801_remove':
i2c-i801.c:(.text+0x1a6126): undefined reference to `i2c_del_adapter'
drivers/built-in.o: In function `dmi_check_onboard_devices':
i2c-i801.c:(.text+0x1a7531): undefined reference to `i2c_new_device'
drivers/built-in.o: In function `i801_probe':
i2c-i801.c:(.text+0x1a7aa8): undefined reference to `i2c_add_adapter'
i2c-i801.c:(.text+0x1a7e14): undefined reference to `i2c_new_device'

So we must select I2C as well.
