boards/arm/olimexino_stm32: Don't enable I2C and SPI

The test "net/utils" fails to build on olimexino_stm32
due to "region `SRAM' overflowed by 192 bytes".

Disabling I2C and SPI on board level the test build fine.

Moreover, according to issue #6858, we will only configure
board valuable HW and connectors on board level and the
user should enable what is needed on application level.
