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.
