1c6d8a9cf4 soc: Remove copyright notices
They're listed in AUTHORS and often incorrect anyway, for example:
- What's a "Copyright $year-present"?
- Which incarnation of Google (Inc, LLC, ...) is the current
  copyright holder?
- People sometimes have their editor auto-add themselves to files even
  though they only deleted stuff
- Or they let the editor automatically update the copyright year,
  because why not?
- Who is the copyright holder "The coreboot project Authors"?
- Or "Generated Code"?

Sidestep all these issues by simply not putting these notices in
individual files, let's list all copyright holders in AUTHORS instead
and use the git history to deal with the rest.

44e9c37f35 mediatek/mt8183: Move some initialization into mt8183_early_init
MT8183 only allows booting from eMMC, so we have to do eMMC emulation
from an external source, for example EC, which makes the size of
bootblock very important.

This CL adds a new function mt8183_early_init, which includes all
initializations that should be done in early stages. All mainboards
using MT8183 should manually call it in either bootblock or verstage.

BUG=b:120588396

9d6523c7db mediatek/mt8183: Remove unused MMU stuff from bootblock
Since we move mtk_mmu_init() from bootblock to decompressor, we don't
need to build mmu_opertations.c in bootblock and we don't need to
include <soc/mmu_operations.h> in bootblock.c.

BUG=b:80501386
TEST=manually flashed into kukui and boots into romstage.

03e9cb9b35 mediatek/mt8183: Enable bootblock self-decompression
MT8183 only allows booting from eMMC, so we have to do eMMC emulation
from an external source, for example EC, which makes the size of
bootblock very important.

A fully functional bootblock (that can boot into verstage or romstage)
is about 38000 bytes. If self decompression (CONFIG_COMPRESS_BOOTBLOCK)
is enabled, only 25088 (66%) bytes are needed.

Inspired from crosreview.com/1070018.
