[PATCH] arm64: dts: qcom: add debug UART pins to reserved GPIO ranges on RB2

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

GPIO12 and GPIO13 are used for the debug UART and must not be available
to drivers or user-space. Add them to the gpio-reserved-ranges.

Fixes: 8d58a8c0d930c ("arm64: dts: qcom: Add base qrb4210-rb2 board dts")
