[PULL 1/4] hw/openrisc: page-align FDT address

[Stafford Horne]

From: "Jason A. Donenfeld" <Jason@zx2c4.com>

The QEMU-provided FDT was only being recognized by the kernel when it
was used in conjunction with -initrd. Without it, the magic bytes
wouldn't be there and the kernel couldn't load it. This patch fixes the
issue by page aligning the provided FDT.
