sun6i: Drop some "unknown magic" from dram init
Allwinner tells us that this bit of code is the rtc ram being used to detect coming out of "super-standby" mode, and if that is the case, going out of self-refresh mode. Since we do not support "super-standby" mode, this can be dropped. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
