be8621d785 soc/mediatek/mt8195: Disable UFS reference clock
UFS reference clock (refclk) is enabled by default, which will cause
the UFSHCI to hold the SPM signal and lead to suspend failure. Since
UFS kernel driver is not built-in, disable refclk in coreboot stage.
Change UFSHCI base register to 0x11270000.

27be90424b soc/mediatek/mt8195: 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.
