ARM: shmobile: kzm9g-reference dts: Declare the full 512 MiB of RAM
Traditionally, the first 16 MiB of RAM was reserved for the RT processor. However, this is incompatible with CONFIG_AUTO_ZRELADDR=y, which requires that the start address of physical memory is a multiple of 128 MiB. As CONFIG_AUTO_ZRELADDR=y is enabled for multi-platform kernels, declare RAM to start at 0x40000000. While at it, reclaim the last 8 MiB of RAM, too, so the full 512 MiB is available. Note that kzm9g_defconfig still has CONFIG_MEMORY_START=0x41000000 and CONFIG_MEMORY_SIZE=0x1f000000, so before the advent of DT we scribbled over the last 8 MiB, too.
