[PATCH V5 3/5] arm64: dts: imx8mm: Add system counter node

[Anson . Huang]

From: Anson Huang <anson.hu...@nxp.com>

Add i.MX8MM system counter node to enable timer-imx-sysctr
broadcast timer driver.

Signed-off-by: Anson Huang <anson.hu...@nxp.com>

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.
