[PATCH] ARM: qcom: add memory node to IPQ806x/AP148

[Mathieu Olivari]

On recent bootloaders, the bootloader patches the DT blob with memory
information. However, with old bootloader, this operation doesn't
happen, which leads the board to freeze in the early init code.

This patch adds the memory node to the AP148 dts explicitly to cover all
boot cases.

Does the old bootloader pass atags? If so we can just enable
CONFIG_ARM_ATAG_DTB_COMPAT and then we don't need to add anything
to dts files.
