ARM: dts: at91: sama7g5: Add can controllers of sama7g5

Add support for all the six CAN controllers of sama7g5.The internal SRAM of 128KB
is split among the CAN controllers for the message RAM elements leaving a small
portion reserved for power management. The SRAM split up is as below.

Lower 64K:
        PM       13K
        can-0    17K
        can-1    17K
        can-2    17K

Higher 64K:

        can-3    17K
        can-4    17K
        can-5    17K
