[PATCH v2 2/5] devfreq: Use %pe to print error pointers symbolically

[Sumeet Pawnikar]

Replace PTR_ERR() and %ld with %pe and pass the original pointer directly
to dev_err(). 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.
