bc2d313d68 board: atmel: sama5d2_icp: enable green led on SPL completion
Enable the green led on SPL completion.
Red led has no pulldown and it will be lighted by default when the
board starts up.
If the PMIC is not configured to enable LDO2, the leds will not light.

2950c514e8 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.

57fbd36c66 board: atmel: sama5d2_icp: add periph reset in SPL hw init
Some periphs on the board need to be reset by holding their reset GPIO down
for a specific time period.
On a warm reset, the periphs are not being reset by any reset pin and may be
in a wrong state.
Reset them in the SPL to make sure we are booting into the correct state
machine of the specific board periphs (KSZ eth switch, USB hub, HSIC eth,
Ethercat)
