platform/x86: x86-android-tablets: Drop "linux,power-supply-name" from lenovo_yt3_bq25892_0_props[]

The "linux,power-supply-name" property is a left-over from an earlier
attempt to allow properties to specify the power_supply class-device name.

The patch to read this property never made it upstream (and is no longer
necessary). Drop the unused property.
