[PATCH linux] boot/dts: Keep the LED initial state during kernel loading

[OpenBMC Patches]

From: johnhcwang <hsienchiang at gmail.com>

Base on the Barreleye HW spec, the beep LED shouldn't be
turned to OFF until BMC ready.

Now the LED will be turned to OFF when the kernel loading,
so enable the LED sub-node property "default-state" to keep the LED
initial state.
