arm64: dts: rockchip: Fix voltage threshold for volume keys for Pinephone Pro
commit 5497ffe305b2ea31ae62d4a311d7cabfb671f54a upstream.
Previously sometimes pressing the volume-down button would register as
a volume-up button. Match the thresholds as shown in the Pinephone Pro
schematic.
Tests:
~ $ evtest
// Mashed the volume down ~100 times with varying intensity
Event: time xxx, type 1 (EV_KEY), code 114 (KEY_VOLUMEDOWN), value 1
Event: time xxx, type 1 (EV_KEY), code 114 (KEY_VOLUMEDOWN), value 0
// Mashed the volume up ~100 times with varying intensity
Event: time xxx, type 1 (EV_KEY), code 115 (KEY_VOLUMEUP), value 1
Event: time xxx, type 1 (EV_KEY), code 115 (KEY_VOLUMEUP), value 0
