The intel-hda model uses an array of register indexed by the
register address. This array also contains a pair of aliased
registers at offset 0x2000. This creates a huge hole in the
array, which ends up eating 4.6MiB of .rodata (size reported
on x86_64 host, building with --extra-cflags=-Os).
By using a memory region alias, we reduce this array to 132kB.
Before:
(qemu) info mtree
00000000febd4000-00000000febd7fff (prio 1, i/o): intel-hda
After:
(qemu) info mtree
00000000febd4000-00000000febd7fff (prio 1, i/o): intel-hda
00000000febd4000-00000000febd7fff (prio 1, i/o): intel-hda-container
00000000febd4000-00000000febd5fff (prio 0, i/o): intel-hda
00000000febd6000-00000000febd7fff (prio 0, i/o): alias intel-hda-alias @intel-hda 0000000000000000-0000000000001fff
