Make sure that dev_<level> calls are newline terminated.
Add #define pr_fmt(fmt) KBUILD_MODNAME ": " fmt to prefix
all pr_<level> calls with "charger-manager: "

Fix a couple of typos.
Fix formats with terminating n that should be \n.
Coalesce formats for easier grep.
Align arguments to open parenthesis for these dev_<level> calls.
Add missing spaces after coalescing multiple string segments.
