mediatek/mt8183: Support DDR frequency 3600Mbps
Add DDR frequency 3600Mbps for EMCP DDR, and fix DDR frequency at 3600Mbps. Since the init setting of freq 3600Mbps is not same as current 3200Mbps, a new init-sequence for 3600Mbps is added. Also, since the mode register value needs to be used at RX gating calibration, we need to implement the mode register init function and use the global variable to make the mode register value the same.
BUG=b:80501386 BRANCH=none TEST=Memory test pass on EMCP platform
