vpp_sel and ethdr_sel are vdosys clock source select mux.
Steps to change to support 4K source.
1. Change vpp_sel source to mainpll_d4 to run at 546MHz
2. Change ethdr_sel source to univpll_d6 to run at 416MHz

eint event mask register is used to mask eint wakeup source.
All wakeup sources are masked by default. Since most MediaTek SoCs do
not have this design, we can't modify the kernel eint upstream driver to
solve the issue 'Can't wake using power button (cros_ec) or touchpad'.
So we add a driver here to unmask all wakeup sources.

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.

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.

MT8195 also uses mt6359p so we can reuse most drivers.
The only differences are IO configuaration, clock setting, and PMIC
internal setting related to soc.
