power: supply: qcom_battmgr: Recognize "LiP" as lithium-polymer

On the Dell Latitude 7455, the firmware uses "LiP" with a lowercase 'i'
for the battery chemistry type, but only all-uppercase "LIP" was being
recognized. Add the CamelCase variant to the check to fix the "Unknown
battery technology" warning.
