soc/mediatek/mt8196: Add version two DPM driver

Add version two of the DPM driver for DVFS and DRAM low power feature.

MT8196 equips new DPM hardware which is different from precedent SoCs.
Therefore, we implement a new DPM loader (said version 2) to run the
blob. The new DPM driver includes following features.
- Simplify the DPM loading flow without the needs of waking DPM SRAM up
  and initializing bootargs.
- Use the broadcast function to ensure that the DPM load and reset
  operations performed on channel A will be synchronized to the other
  three channels.

TEST=Full calibration pass.
