Bugfix: set battery percentage correctly after RTE update When the RTE is rebooted, the battery percentage on the display is zeroed. However, when selecting SYS2-reboot-maintenance, the previously known battery percentage can be manually restored. Interestingly, when the restore reported a percentage A, choosing that resulted in a percentage B to be displayed again. With B much smaller than A. So, rebooting the RTE multiple times resulted in an seemingly empty battery, while it definitely is not. The reason for this is a relatively simple bug in the RTE code. This commit fixes the conversion between the internal LTC2941 registers and the percentage value to be displayed. Obviously, from and to the internal registers need to be symmetrical.
