vendor: mediatek: Add mediatek mt8192 dram initialization code

This is the DRAM initialization code from the reference
implementation released by Mediatek for MT8192.

The DRAM calibration code can be taken as a standalone
library, used by different boot loaders for initializing
DRAM and following a different coding style (coreboot was
using Linux Kernel coding style), so we have to put it
in vendor code folder.
