mvebu: backport DTS changes for Turris Omnia from mvebu/dt

Browse Source 
My commit backported patches from the following links:
- https://lore.kernel.org/linux-arm-kernel/20220704113622.18887-1-kabel@kernel.org/
- https://lore.kernel.org/linux-arm-kernel/20220704113622.18887-2-kabel@kernel.org/

According to the links, they are applied in repository mvebu in branch dt,
so it should be included in upcoming Linux version soon.

Subject: [PATCH] ARM: dts: turris-omnia: configure LED[0] pin function to
link/activity
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The marvell PHY driver changes the LED[0] pin function to "On - 1000
Mbps Link, Off - Else".
Turris Omnia expects that the function is "On - Link, Blink - Activity,
Off - No link".
Use the `marvell,reg-init` DT property to change the function.
In the future, once netdev trigger will support HW offloading, we will
be able to have this configured via the combination of PHY driver and
leds-turris-omnia driver.

Subject: [PATCH] ARM: dts: turris-omnia: enable LED controller node
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The LED controller node is disabled because the leds-turris-omnia driver
does not support setting the LED blinking to be controlled by the MCU.
The patches for that have now been sent [1], so let's enable the node.
