Implement ms timer and fix all timers This will fix everything that uses a timer (or sleep). Without this any function like eMMC/SD read/write/verify, TSEC/SE, etc can break when the time reaches the max value of the u32 microsecond timer (71minutes).

main: Add empty battery screen This disables low battery monitor shutdown (LBM shutdown) on boot and checks if battery is enough. The logic is as follows: If battery is not enough: - If not charging and 15s pass, it will re enable LBM shutdown and power off. - If charging, it will wait until it is charged above the limit. Screen will auto turn off to save power. A press on Power button or a change on charger, will enable it for another 15s. If battery is enough: - Enables LBM shutdown and continues with the boot process.
