Shiji Yang 6f33529a12 mediatek: dts: fix the broken memory node 
Add the missing "device_type" property to fix the memory node. The
Linux kernel can not get the memory size without it. Though u-boot
can automatically fixup the memory node by adding the "device_type"
and "reg" properties if the CONFIG_ARCH_FIXUP_FDT_MEMORY symbol is
enabled, it's better not to rely on this optional feature. This
patch also adds the reg address for the memory node name to follow
the naming rules.
