ARM: dts: at91: Configure I2C SCL gpio as open drain

The SCL gpio pin used by I2C bus for recovery needs to be configured as
open drain.

Fixes: 455fec93 ("ARM: dts: at91: sama5d2: add i2c gpio pinctrl")
Fixes: a4bd8da8 ("ARM: dts: at91: sama5d3: add i2c gpio pinctrl")
Fixes: 8fb82f05 ("ARM: dts: at91: sama5d4: add i2c gpio pinctrl")
