Subject: [PATCH] extcon: Provide *extcon_*_notifier_all() stubs for
 !CONFIG_EXTCON

CHARGER_MAX8997 fails to compile without CONFIG_EXTCON. There are stubs
already present for *extcon_*_notifier() but are missing for the _all()
variant.

Add *extcon_*_notifier_all() stubs for !CONFIG_EXTCON.

Fixes: f384989e88d44 ("power: supply: max8997_charger: Set CHARGER current limit")
