arm64: dts: qcom: sdm845-oneplus: fix fuel gauge compatible

The fuel gauge at I2C address 0x55 on OnePlus 6T (fajita) reports DeviceType 0x0541, identifying it as a TI bq27541 rather than bq27411.

Binding it as bq27411 selects the wrong register map and produces invalid voltage, state-of-charge, and temperature readings. Use the bq27541 compatible and rename the shared label along with its fajita and enchilada consumers.

Tested on OnePlus 6T (fajita): queried DeviceType directly over I2C, built the DTB, booted it once with fastboot boot, then installed a locally built postmarketOS kernel package. Before the change, readings included about 65 V, over 10000% SOC, and -273.1 C. Afterward, the bq27xxx driver bound as ti,bq27541 and reported 3.835 V, 42% SOC, and 33.3 C.
