[PATCH] ARM: dts: exynos: correct trats2 panel reset line

[Simon Shields]

trats2 uses gpf2-1 as the panel reset GPIO. gpy4-5 was only used
on early revisions of the board.

It looks that this has been accidentally copy/pasted from the previous
dts used for early version of the development board. I've checked the
Trats2 schematic and indeed gpf2-1 is the correct pin for panel reset
line.

Thanks for testing.

Thanks, applied.
