oak: increase the PMIC power key press time to 5 seconds.
There are 3 methods to power on the system: 1) Pulling PWRKEY low (User presses PWRKEY) 2) Setting BBWAKEUP high 3) Valid charger plug-in We should ensure that BBWAKEUP should be high when release PWRKEY. Due to the RTC driver of coreboot will move to ramstage, and the setup timing of BBWAKEUP will be postpone. In order to ensure PMIC keeping the power until coreboot pull BBWAKEUP up, it needs to increase the PMIC power key press time to avoid PMIC turn the power off. This change is related to: https://chromium-review.googlesource.com/#/c/257389/ BRANCH=none BUG=none TEST=manual Update coreboot with above patch, press power key and system should power on normally.
