Nokia RX-51: Decrease i2c speed to 100000

Browse Source 
It looks like that i2c bus lot of times timeout on some units. Prior
migration to CONFIG_DM_I2C i2c speed was set to CONFIG_SYS_OMAP24_I2C_SPEED
value which was 100000. Lower speed fixes timeout problems, so change speed
back to its previous value.
