[PATCH] Revert "ARM: Use armlinux_bootparams address for DTB"

[Sascha Hauer]

This patch placed the flattened devicetree to armlinux_bootparams.
armlinux_bootparams normally is at SDRAM_START + 0x100. The kernels
initial page tables are normally at SDRAM_START + 0x4000, so the
flattened devicetree gets overwritten once it exceeds 0x3f00 bytes
which is quite common.

Revert this patch for now once a better solution can be found

This reverts commit 0c4108f9173ece75d96f19b447ef6464bdfdf187.
