So, this makes it impossible to add a "reg" property(used in of_phy_led())
for hibmcge. Therefore, the PHY_LED framework cannot be used directly.
This patch creates a separate LED device for hibmcge
and directly calls the phy->drv->led_hw**() function to
operate the related LEDs.
Documentation/firmware-guide/acpi/dsd/phy.rst
