ram: stm32mp1: Conditionally enable ASR
Enable DRAM ASR, auto self-refresh, conditionally, based on DT PWRCTL register bits. While ASR does save considerable amount of power at runtime automatically, it also causes LTDC underruns on large panels. Let user select whether or not ASR is required or not, generally ASR should be enabled on portable and battery operated devices.
