mediatek/mt8183: Add a stub implementation of the MT8183 SOC
Most things still need to be filled in, but this will allow us to build boards which use this SOC. BUG=b:80501386 BRANCH=none TEST=timer and uart work fine Change-Id: Ie81fa56ffce85188e1f9e979f9b0e64b764c2627 Signed-off-by: Tristan Shieh <tristan.shieh@mediatek.com> Reviewed-on: https://review.coreboot.org/26659 Reviewed-by: Patrick Georgi <pgeorgi@google.com> Reviewed-by: Hung-Te Lin <hungte@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
