ASUS F2A85-M: romstage.c: Set RAM voltage for non 1.5 Volt case

Currently the if statement

if (!byte)
        	do_smbus_write_byte(0xb20, 0x15, 0x3, byte);

only gets executed if `byte == 0x0`, that means only in the
    default case where RAM voltage is 1.5 Volts. But the RAM voltage
    should be changed when configured for the non-default case.

So change the predicament to alter the RAM voltage for the
    non-default cases.

To prevent the build error

OBJCOPY    cbfs/fallback/coreboot_ram.elf
        coreboot-builds/asus_f2a85-m/generated/crt0.romstage.o: In function `cache_as_ram_main':
        /srv/jenkins/.jenkins/jobs/coreboot-gerrit/workspace/src/mainboard/asus/f2a85-m/romstage.c:106: undefined reference to `do_smbus_write_byte'
        collect2: error: ld returned 1 exit status
        make: *** [coreboot-builds/asus_f2a85-m/cbfs/fallback/romstage_null.debug] Error 1

add `southbridge/amd/agesa/hudson/smbus.c` providing the function
    `do_smbus_write_byte` to ROM stage in `Makefile.inc`.
