[PATCH 2/4] net: i825xx: Use absolute_pointer for memcpy on fixed memory location

[Guenter Roeck]

gcc 11.x reports the following compiler warning/error.

drivers/net/ethernet/i825xx/82596.c: In function 'i82596_probe':
    ./arch/m68k/include/asm/string.h:72:25: error:
            '__builtin_memcpy' reading 6 bytes from a region of size 0
                    [-Werror=stringop-overread]

Use absolute_address() to work around the problem.
