Like we are doing on DDR0 we need to cleanly shutdown DDR1 if it is
used before rebooting.
If DDR1 is not initialized, we check it and avoid dereferencing its address.
Even by adding two more instructions, we are able to complete the procedure
within a single cache line.

As on the other sam9 we need to cleanly shutdown the DDRAM before rebooting.
On those SoC the SDRAM/DDRAM controller is different. So, the assembly code
ends up being not cleanly combined with previous at91sam9_alt_restart function.
