Subject: [PATCH] brcm63xx: allow lzma to use 32MB RAM

Most 16 MiB RAM devices don't even load elf kernels, so it's safe to
assume we have at least 32 MB RAM. This fixes tftp booting with the
default package set as this already produces an uncompressed
kernel > 8 MiB.

New limit is 8 MiB compressed / 24 MiB compressed.
