powerpc: dts: turris1x.dts: Add channel labels for temperature sensor
[ Upstream commit 67bbb62f61e810734da0a1577a9802ddaed24140 ] Channel 0 of SA56004ED chip refers to internal SA56004ED chip sensor (chip itself is located on the board) and channel 1 of SA56004ED chip refers to external sensor which is connected to temperature diode of the P2020 CPU.
