[PATCH 1/2] ARM: stm32: Define I2C EEPROM bus and address on DHCOM

[Marek Vasut]

Define I2C EEPROM bus and address, so that the 'eeprom' command uses
the correct ones and does not generate the following error:
    eeprom_rw_block: Cannot find udev for a bus 0

[PATCH 2/2] ARM: stm32: Hog GPIO PF7 high on DHCOM to unlock SPI NOR nWP

[Marek Vasut]

The SPI NOR nWP line is connected to GPIO PF7 on the SoM,
pull the GPIO line high by default to clear SPI NOR WP.
