Subject: [PATCH V3 2/2] ARM: dts: imx6sx-sabreauto: add external 24MHz clock source

On i.MX6SX SabreAuto board, there is external 24MHz clock
source for analog clock2, add this clock source to clock tree
and remove "clocks" container for all input clocks.

Signed-off-by: Anson Huang <Anson.Huang@....com>
---
changes since V2:
	remove "clocks" container and use new way for all input clocks definition.
