soc/mediatek/mt8186: Enable mmu operation for L2C SRAM and DMA
1. 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.
2. Configure DMA buffer in DRAM
Set DRAM DMA to be non-cacheable to load blob correctly.
