soc/mediatek/mt8183: Pass MR values as function arguments
To make data flow more explicit, global variables 'MR01Value' and 'MR13Value' are replaced with local variables, which are passed as function arguments. BRANCH=kukui BUG=none TEST=1. emerge-kukui coreboot 2. Fast calibration succeeded Change-Id: Id21483092c86c3ae7dbb1173a2b943defe41a379 Signed-off-by: Yu-Ping Wu <yupingso@chromium.org> Reviewed-on: https://review.coreboot.org/c/coreboot/+/36286 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Hung-Te Lin <hungte@chromium.org>
