arm64: dts: qcom: x1-dell-thena: remove i2c20 (battery SMBus) and reserve its pins

Browse Source 
i2c20 is used by the battmgr service on the ADSP to communicate with the
SBS interface of the battery. Initializing it from Linux would break the
battmgr functionality when booted in EL2. Mark those pins as reserved.
