mediatek/mt8183: support get current DRAM type

Read the ramid to get the DRAM type of current platform.
For EMCP DDR, the max support DRAM frequency was 3600Mbps,
but for DISCRETE DDR, the max support DRAM frequency was 3200Mbps.
So for different DDR type, need do different DDR init flow.

BUG=b:80501386
BRANCH=none
TEST=Memory test passes on EMCP platform
