soc/mediatek/mt8196: Reserve DRAM buffers for HW TX TRACKING

HW TX tracking works by writing a pattern to the designated DRAM buffer
and then reading it back automatically to calculate the appropriate TX
time delay. To avoid writing the pattern to system-used memory, we need
to reserve a dedicated buffer for HW TX tracking feature.

BUG=b:317009620
TEST=Reserve memory ok
