[PATCH 5/5] power: Use %pe to print error pointers symbolically

[Sumeet Pawnikar <sumeet4linux@gmail.com>]

Replace PTR_ERR() and %ld/%li with %pe and pass the original pointer
directly to dev_info(), dev_warn(), dev_err() and dev_dbg(). The %pe
format specifier prints a symbolic error name (e.g. -ENOMEM) when
CONFIG_SYMBOLIC_ERRNAME is enabled, otherwise it falls back gracefully
and prints the raw integer value. This makes messages more readable
without any functional change.
