soc/mediatek/mt8186: Enable CPU power hardware tracking for PMIC MT6366
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.
