mediatek/mt8183: Implement the dramc init setting

This patch implements the dram init setting by replacing the hard-coded
init sequence with a series of functions to support calibration for more
frequencies. These functions are modified from MediaTek's internal DRAM
full calibration source code.

BUG=b:80501386
BRANCH=none
TEST=1. Kukui boots correctly
     2. Stress test (/usr/sbin/memtester 500M) passes on Kukui
