power: supply: qcom_battmgr: Add lithium-polymer entry

On some Dell XPS 13 (9345) variants, the battery used is lithium-polymer
based. Currently, this is reported as unknown technology due to the entry
missing.

[ 4083.135325] Unknown battery technology 'LIP'

Add another check for lithium-polymer in the technology parsing callback
and return that instead of unknown.
