Subject: [PATCH 09/15] arm64: dts: qcom: msm8992-libra: Fix up the framebuffer

Make sure the necessary clocks are kept on after clk_cleanup (until MDSS
is properly handled by its own driver) and touch up the fb address to
prevent some weird shifting. It's still not perfect, but at least the
kernel log doesn't start a third deep into your screen..
