soc/mediatek/mt8188: Enable mmu operation for L2C SRAM and DMA

- Turn off L2C SRAM and reconfigure as L2 cache:
  Mediatek SoC uses part of the L2 cache as SRAM before DRAM is ready.
  After DRAM is ready, we should invoke disable_l2c_sram to reconfigure
  the L2C SRAM as L2 cache.

- Configure DMA buffer in DRAM:
  Set DRAM DMA to be non-cacheable to load blob correctly.
