mfd: Kconfig: Fix I2C_DESIGNWARE_PLATFORM dependencies

[ Upstream commit 09fdc985 ]

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:

WARNING: unmet direct dependencies detected for I2C_DESIGNWARE_PLATFORM
  Depends on [n]: I2C [=y] && HAS_IOMEM [=y] && (ACPI [=y] && COMMON_CLK [=n] || !ACPI [=y])
  Selected by [y]:

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.
