board: atmel: sama5d2_icp: standby disable on CAN transceivers in SPL

The 2 CAN transceivers have a STBDY pin which must be low in order to
operate.
This pin is tied to PB25.
Set it to 0 in bootstrap.
At a later time, this needs to be controlled by Linux power management
system, or requested by some driver as a gpio and tied to 0 during
CAN link up.
