Input: adp5588-keys - unify common header defines
Unify adp5588-gpio and adp5588-keys common header defines (as per Andrew Morton request). For consistency, move remaining defines and prefix accordingly. No functional changes. Signed-off-by: Michael Hennerich <michael.hennerich@analog.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
