This adds the Kconfig option to specify default configuration
for the I2C controller during driver initialization.
During boot, the controller needs to be configured before
communication to slave devices can start. After boot,
an app can re-configure the controller if needed.

All supported platforms have descending stack (growth direction is
down). To avoid confusion just remove not needed stack direction
defines.
If new platform with stack direction up is added is should be
configured by adding Kconfig option eg STACK_GROWS_UP and
CONFIG_STACK_GROWS_UP should be used in code that depends on
stack growth direction.
