Revert "TPM: ACPI/PNP dependency removal"

Browse source 
This reverts commit b89e66e1e3.

> > When CONFIG_PM is not set:
> >
> > drivers/built-in.o: In function `acpi_init':
> > bus.c:(.init.text+0x2d84): undefined reference to `pm_flags'
> > bus.c:(.init.text+0x2d91): undefined reference to `pm_flags'
>
> CONFIG_ACPI depends on CONFIG_PM,
> so acpi/bus.c should not be compiled for CONFIG_PM=n
>
> Hmm, is is somebody doing something strange, like "select ACPI"
> without guaranteeing that all of ACPI's dependencies are satisfied?

obtained at: <http://sourceforge.net/projects/trousers>. To
compile this driver as a module, choose M here; the module
will be called tpm. If unsure, say N.
Note: For more TPM drivers and BIOS LOG access enable
CONFIG_PNP, CONFIG_ACPI and CONFIG_PNPACPI.
Note: For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
and CONFIG_PNPACPI.
if TCG_TPM
config TCG_TIS
tristate "TPM Interface Specification 1.2 Interface"
depends on PNP
---help---
If you have a TPM security chip that is compliant with the
TCG TIS 1.2 TPM specification say Yes and it will be accessible
from within Linux. To compile this driver as a module, choose
M here; the module will be called tpm_tis.
config TCG_BIOS_LOG
bool "TPM bios mesurement log"
depends on X86
select ACPI
---help---
ACPI is required for access to bios measurements lists and therefore
to validate the PCR[0] value. So say Yes in case you want this
feature and, consequently, ACPI will be enabled.
config TCG_NSC
tristate "National Semiconductor TPM Interface"
