Subject: [PATCH] mfd: Kconfig: Fix I2C_DESIGNWARE_PLATFORM dependencies

INTEL_SOC_PMIC, INTEL_SOC_PMIC_CHTWC and MFD_TPS68470 select the I2C_DESIGNWARE_PLATFORM without its dependencies making it possible to see warning and build error like below:

Fix this by making above options to depend on I2C_DESIGNWARE_PLATFORM being built-in. I2C_DESIGNWARE_PLATFORM is a visible symbol with dependencies so in general the select should be avoided.
