[ Upstream commit a0cac264a86fbf4d6cb201fbbb73c1d335e3248a ]
The devm_gpiod_request_gpiod() call will add "-gpios" to any passed connection ID before looking it up.
I do not think the reset GPIO on this platform is named "reset-gpios-gpios" but rather "reset-gpios" in the device tree, so fix this up so that we get a proper reset GPIO handle.
Also drop the inclusion of the legacy GPIO header.
