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.
