The camera driver reduced all IO drivers from their reset defaults of
6 mA to only 2 mA, which caused severe signal distortion at higher
speeds. This patch sets them to 8 mA and also removes apparently
useless repetitions of the setting.
Note that the correct setting of the I2C pullups still needs to be
verified.
