HID: Add and use hid_<level>: dev_<level> equivalents

Neaten current uses of dev_<level> by adding and using
hid specific hid_<level> macros.

Convert existing uses of dev_<level> uses to hid_<level>.
Convert hid-pidff printk uses to hid_<level>.

Remove err_hid and use hid_err instead.

Add missing newlines to logging messages where necessary.
Coalesce format strings.

Add and use pr_fmt(fmt) KBUILD_MODNAME ": " fmt

Other miscellaneous changes:

Add const struct hid_device * argument to hid-core functions
extract() and implement() so hid_<level> can be used by them.
Fix bad indentation in hid-core hid_input_field function
that calls extract() function above.
