* Use SysTick as OS tick timer * Use LPTIM2 as tickless idle timer * Remove dummy LPTIM2 IRQ handler * Clean up clock init code * Rename os timer to idle timer * Advance hal ticks along with FreeRTOS's * Improve SysTick control during tickless idle * Improve idle timer precision * Correct SysTick IRQ priority * Main, FuriHal: move system startup to separate thread * Minor code cleanup Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
