[PATCH V5 4/5] arm64: dts: imx8mq: Add system counter node

[Anson.Huang@xxxxxxx]

From: Anson Huang <Anson.Huang@xxxxxxx>

Add i.MX8MQ system counter node to enable timer-imx-sysctr
broadcast timer driver.

Signed-off-by: Anson Huang <Anson.Huang@xxxxxxx>

Changes since V4:
	- update the clock info using fixed clock node;
	- correct the reg range;
	- update the interrupt number as the system counter driver ONLY uses 1 irq now.
