Let's make it consistent with battery code; also it fixes HAL case of=20
duplicated adapters. Somebody will have to sort out HAL with ACPI_PROCFS=20
case ...

Subject: [PATCH] 2.6.24: make /proc/acpi/ac_adapter dependent on ACPI_PROCFS
=46rom: Andrey Borzenkov <arvidjaar@mail.ru>

Do not provide /proc/acpi/ac_adapter if ACPI_PROCFS is not defined.
This eliminates duplicated power adapters in HAL and makes it consistent
with battery module
