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

This change adds about 30 KiB to FSP-M. When not using the SPI DMA
controller, this change actually has a ~7 ms boot time penalty. When
we use the DMA engine, we end up with about a 5 ms decrease. Once we
switch to 100 MHz SPI this will help even more since we have effectively
eliminated the decompression time.
