Subject: [PATCH 55/57] power: ab8500_charger: Add UsbLineCtrl2 reference

From: Marcus Cooper <marcus.xm.cooper@...ricsson.com>

When the state of USB Charge detection is changed then the calls
use a define for another register in other bank. This change
creates a new define for the correct register and removes the
magic numbers that are present.
