malta: move to 4.4 kernel

Linux now has device tree support for malta.  The patch for correcting
/proc/iomem content is not needed now.  Previously it was

    root@(none):/# cat /proc/iomem
    00000000-00000fff : reserved
    00001000-000effff : System RAM
    000f0000-000fffff : reserved
    00100000-0fffefff : System RAM
      00100000-003f2b6b : Kernel code
      003f2b6c-00485937 : Kernel data
    ...

Now it's

    root@OpenWrt:/# cat /proc/iomem
    00000000-0fffefff : System RAM
      00100000-004a3297 : Kernel code
      004a3298-0057cfff : Kernel data
    ...

The kernel config was prepared as follows

 1. cp target/linux/malta/config-{3.18,4.4}
 2. make kernel_menuconfig CONFIG_TARGET=subtarget_platform

-Subject: [PATCH 330/331] MIPS: Malta: Mark kernel code and kernel data
- segments as BOOT_MEM_RAM.
-
-Kexec-tools requires those segments listed as "System RAM" in
-/proc/iomem, otherwise, an error message of "Invalid memory segment"
-will be emitted when trying to load the ELF kernel image.
