2022-09-09soc/mediatek/mt8186: Enable CPU power hardware tracking for PMIC MT6366Sen Chu
1. There are two power sources for CPU: - Logic power (VPROC). - SRAM power (VSRAM_PROC). 2. There is a constraint between VPROC and VSRAM_PROC: - 0mV <= VSRAM_PROC - VPROC <= 250mV. With software control, the constraint might not always hold. Therefore, we enable hardware tracking from PMIC MT6366 to ensure the constraint is met automatically. BUG=b:236353282, b:241615706 TEST=meet the constrain correctly when adjusting the voltage.

2022-05-09soc/mediatek/mt8186: Change the power-down time slot from 0xA to 0xFzhiyong tao
PMIC_CPSDSA4[4:0] controls the power-down at the specified time slot. Setting it to 0xA would cause an extra delay of 20ms compared to 0xF. The value of time slot is from 0x0 to 0x1F which represents the delay when reset occurs. To avoid the delay, change the value from 0xA to 0xF. This modification is based on chapter 3.7 in the MT8186 functional specification. BUG=b:218630683, b:218630684 TEST=the power-off waveform is correct.

2022-03-29soc/mediatek/mt8186: Fix pmif setting for low power modeZhiyong Tao
The current pmif register setting for low power mode is incorrect, which is causing suspend failure. The issue of suspend failure is that SRCLKENA0 will not be pulled down. EC will not be informed AP is suspending now becuase of this. Therefore, add pmif_spmi_set_lp_mode() to correct the setting. This implementation is based on chapter 3.7 in MT8186 Functional Specification. BUG=b:215639203 TEST=test of suspend and resume pass.
