This patch removes the default value from some platform/SoC specific
options which are declared in drivers/i2c/Kconfig because 1) most of
the time they are not valid values and 2) the correct values are
already set in the SoC Kconfig.
It also moves the interrupt priority definition from the driver's
Kconfig to the platform's Kconfig since it is a platform-specific
configuration.
