tpm: change Kconfig dependencies from PNPACPI to PNP

There is no "PNPACPI" driver interface as such. PNPACPI is an internal
backend of PNP, and drivers just use the generic PNP interface.

The drivers should depend on CONFIG_PNP, not CONFIG_PNPACPI.

tpm_nsc.c doesn't use PNP at all, so we can just remove the dependency
completely. It probably *should* use PNP to discover the device, but until it
does, there's no point in depending on PNP.
