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 permanently reserve last 64KB memory on each rank for the HW TX tracking feature.
BUG=b:317009620 TEST=Reserve memory ok Firmware shows the following log with 12GB DDR board: 00000001ffff0000-00000001ffffffff: RESERVED 000000037fff0000-000000037fffffff: RESERVED
