arm64: dts: rockchip: Fix voltage threshold for volume keys for Pinephone Pro

Browse source 
commit 5497ffe305 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
