In order to support low power state, you must source kernel system
timers to persistent clock, available across suspend/resume. In case of
AM335x device, the only source we have is, RTC32K, available in
wakeup/always-on domain. Having said that, during validation it has
been observed that, RTC clock need couple of seconds delay to stabilize
the RTC OSC clock; and such a huge delay is not acceptable in kernel
especially during early init and also it will impact quick/fast boot
use-cases.
So, RTC32k OSC enable dependency has been shifted to
SPL/first-bootloader.
