Alexander Graf 76e2aef392 hw/arm/boot: Increase fdt alignment 
The Linux kernel on aarch64 creates a page table entry at early bootup
that spans the 2MB range on memory spanning the fdt start address:

  [ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ]

This means that when our current 4k alignment happens to fall at the end
of the aligned region, Linux tries to access memory that is not mapped.

The easy fix is to instead increase the alignment to 2MB, making Linux's
logic always succeed.

We leave the existing 4k alignment for 32bit kernels to not cause any
regressions due to space constraints.
