Enable the impedance tracking for channel 2 and channel 3.
The impedance tracking can compensate the settings of impedance
when the temperature changes.

Add the implementation for vcore voltage control.
Also remove the reporting of vio18 because it is fixed during DRAM init,
and we won't provide drivers for reading or writing it.

The CONFIG(CHROMEOS) in DRAM calibration code was incorrectly used to
identify implementations for Chromebooks (in coreboot) so we want to
introduce a new flag FOR_COREBOOT to prevent confusion.

To support DRAM HQA HV/LV test, add an interface for adjusting the DRAM
voltage in DRAM fast calibration flow.
Normal boot flow will not be affected.

This is the DRAM initialization code from the reference
implementation released by Mediatek for MT8195.
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.

gcc 11.1 complains when we're passing a type* into a function that was
declared to get a type[], even if the ABI has identical parameter
passing for both.
To prepare for newer compilers, adapt to this added constraint.

Originally, log macro names are too long, and they use
double parentheses style: ((...)), which causes compile
or runtime error easily.
Now, change them to single parenthesis mode (...), and
use shorter name.
