Subject: [PATCH 11/11] platform: cznic: turris-omnia-mcu: fix Kconfig
dependencies
The newly added driver causes a Kconfig warning:
WARNING: unmet direct dependencies detected for RTC_CLASS
Depends on [n]: !S390 [=y]
Selected by [m]:
- TURRIS_OMNIA_MCU [=m] && CZNIC_PLATFORMS [=y] && (MACH_ARMADA_38X || COMPILE_TEST [=y]) && I2C [=m] && OF [=y] && WATCHDOG [=y]
The problem here is that it selects entire subsystems, which normal
device drivers should not do. Changes all of these to 'depends on'
instead.

Fixes: 90e700fd12b61 ("platform: cznic: turris-omnia-mcu: Add support for poweroff and wakeup")

Say Y here to add support for the features implemented by the
microcontroller on the CZ.NIC's Turris Omnia SOHO router.
