net: pse-pd: tps23881: Fix current measurement scaling

[ Upstream commit 2c95a75 ]

The TPS23881 improves on the TPS23880 with current sense resistors reduced
from 255 mOhm to 200 mOhm. This has a direct impact on the scaling of the
current measurement. However, the latest TPS23881 data sheet from May 2023
still shows the scaling of the TPS23880 model.
