mediatek/mt8183: Use different DRAM frequencies for eMCP DDR
Devices using eMCP may run at a high DRAM frequency (e.g., 3600Mbps)
while those with discrete DRAM can only run at 3200Mbps. This patch
enables 3600Mbps for eMCP DDR for better system performance.
BUG=b:80501386
BRANCH=none
TEST=Boots correctly and stress test passes on Kukui
