[PATCH v2] arm64: dts: exynos: Add flash led dt node for TM2 board

[Chanwoo Choi]

Dear Seung-Woo,

I think that this patch looks good to me.
But, When I tested this patch on my TM2 board,
the flash turn off after some millisecond automatically.

It is strange situation. Unfortunately, I don't know the cause.
I think that we better to check this issue for more time.

Best Regards,
Chanwoo Choi

Thank you for testing on your side. I will check on my side about the
issue, and if I find, then I will send next version.
