[PATCH 7/7] Revert "ACPI: ibm-acpi: make non-generic bay support optional"

[Len Brown <len.brown@intel.com>]

From: Henrique de Moraes Holschuh <hmh@hmh.eng.br>

This reverts commit 2df910b4c3edcce9a0c12394db6f5f4a6e69c712.

ACPI_BAY has not been merged into mainline yet, so the changes to ibm-acpi
related Kconfig entries that depend on ACPI_BAY were permanently disabling
ibm-acpi bay support.  This is a serious regression for ThinkPad users.
