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.
