Subject: [PATCH] arm64: dts: sun50i-a64-pinephone: improve brightness values
on BH/CE
Commit aad90c10 caused a brightness increase with the previous values.
Subsequently, the lowest brightness value would still be fairly bright.
This commit aims at providing a wider range of usable brightness for
1.1+ devices.
