[PATCH v3 2/2] arm: Clean up linker script using new linker script macros.

[Tim Abbott]

From: Nelson Elhage <nelhage at ksplice.com>

This patch is mostly a straightforward translation. The primary side
effect to the resulting vmlinux should be to increase the alignment on
the initramfs to the standard PAGE_SIZE from 32 bytes.
